Why Pick A Carbon Fiber Hockey Stick

Ask any player about which piece of sports equipment is the most essential in the game of hockey and the unanimous answer would no doubt be the hockey stick. Hockey, a highly physical contact sport wherein engaging in fisticuffs is as legal as a slapshot, can be played sans a puck and without donning skates, helmets, and protective gear, but never without a stick.

While there are a plethora of sticks that a player can choose from, a carbon fiber hockey stick has proven its durability and proficiency, making it the favorite of both the novice and professional. Read on as we talk about everything hockey stick to get a firm grasp on the tool that makes for an epic wrist shot.

Hockey Stick Types

It’s no secret how hockey players uphold their sticks in high regard. Not only are hockey sticks often a source of pride, but they are also frequently a crucial part of a player’s game routine which they allot a significant amount of time and energy in to ensure that their stick is as ready as they are before hitting the ice. Known as one of the most customizable sports equipment, here are a few tips on finding the perfect hockey stick.

Wood Stick

Typically crafted from several layers of various wood types, a wooden stick is a much heavier variety that provides good resistance and grit. Previously the choice of NHL players, wooden sticks remain to be a favorite when it comes to the comfort of use and maneuverability, making them an ideal choice for field or street hockey and the budding hockey player.

If you aim to play up your hockey game then a high-quality stick is what you want. Composite sticks are lighter, stiffer yet more flexible, but also more expensive when compared to their wooden peer. Often made from a blend of fiberglass, Kevlar, graphite, carbon fibers, and a little bit of wood, composite sticks are capable of snapping back to its original form even after being flexed and bent out of shape from extreme pressure or shock.

Picking the right hockey stick can spell the difference between a mediocre game and superior handling, shooting, and overall puck control. Apart from the gains that a technologically advanced hockey stick can offer, an excellent pick can raise your hockey game to a whole different level.

Why Should I Stick With A Carbon Fiber Hockey Stick?

If the price is not an issue, a carbon fiber hockey stick should be your pick. Carbon fiber is a light material that makes plastic seem like a heavyweight. Generally used in other sports equipment such as baseball bats, golf clubs, as well as tennis and badminton rackets, its utmost durability and lightweight features make it the preferred fabric of both enthusiasts and professionals.

The material’s agility enables a player to swing his hockey stick effortlessly while its superior flexibility allows it to withstand not just intense twists and bends but severe spikes in temperature, particularly the coldness of the ice, as well. Carbon fiber hockey sticks, with their wear-and-tear, corrosion, and low-temperature resistance, may well be the best and most reliable twig in all of hockey.

What Are The Benefits Of A Carbon Fiber Hockey Stick?

Hockey sticks play a major role in a competitor’s performance. This integral tool that affects the hockey player’s handling and shooting skills should provide a better feel, must weigh much less, and ought to be highly durable. Here’s a rundown on the superiority of this state-of-the-art hockey stick.

Weightless

Unmistakably, sticks made of carbon fiber are much lighter than their wooden counterpart of the same specs and length. This provides better handling as you skate around the rink in pursuit of the puck and more power behind your shots to hurl pass that pesky goalie.

Longer Lasting

With composite materials used as its main fabric, carbon fiber hockey sticks are fashioned with durability in mind. Although it is not completely free from cracks and breaks, it promises countless hard, accurate shots over a long period.

Uniform Quality

In terms of material, wooden sticks are less consistent than carbon fibers. The wood varies in every piece, resulting in microscopic differences in each hockey stick.

Tailor-Made

Perhaps one of the most helpful benefits of carbon fiber hockey sticks is that players can modify them to cater to their personal preferences. Customize your piece from the kick point to its flex and blade pattern, all to pave the ice for you to become an epic hockey player.

Gone are the days when you show up on the rink and impress other players with your wooden hockey stick. Carbon fiber has changed the way the game of hockey is played since it provides better puck control and stronger, harder, and more precise attacks.

Carbon Fiber Hockey Stick Cost

Great sticks come with great ability… and cost.

Gone are the days when you could walk into a sports equipment store and stumble upon hockey sticks that costs $25-30$. Nowadays, a quality stick would pinch your wallet for about $150-$300 with the vow that each piece possess exceeding and sheer endurance. Hockey sticks of today are made of plastic and foam fortified by fiber. No doubt, they would hold you back a little more compared to a wooden stick, but its high compressive strength creates a sturdy, high-performance material. Carbon fibers are lightweight and stiff threads have high tensile strength. Bundle thousands of them together and they form what could be one of the most durable materials ever.

Obviously, carbon fiber is way more expensive to manufacture and source than wood. This explains why this hockey stick cost a tad higher than its wooden peers. Here are a few key points:

• Carbon fiber which is typically used in Formula 1 racing, is a resource and energy-intensive material meaning it is generally held for priority industries such as military defense and rocket ships.
• Compared to crafting raw timber, shaping carbon fiber requires more work. The sticks physical aspects are first conceptualized, designed and tested, soon after expert craftsmen meticulously manufacture the stick, before it is elaborately decorated, packed and shipped.
• NHL Players with the likes of the great Wayne Gretzky are tapped to entice us to purchase these ridiculously amazing sticks, putting a little more weight on the hockey stick price tag.

Much like tennis rackets and golf shafts, carbon fiber sticks simply define the evolution of hockey sticks. The $150-$200 variant should be a good enough weapon for the beginner, while the pricier versions which cost around $200-$300 should do wonders for the highly-competitive and professionals. Bear in mind that although a good stick provides you with a slight advantage, it does not affect your wrist shot’s quality.

We encourage you to get in touch with us and it would be our pleasure to provide you with details and information on the hockey sticks that best will best suit you.

Conclusion 

For its consistency, reduced weight, and increase in shot velocity, carbon fiber hockey sticks offer the best bang for your buck. There might still be some who would tell you that wood plays better but wouldn’t it be cool to ring that bell with a solid stick.

TOVI Hockey Stick Seeks NHL Approval – Sportico.com

The NHL will review a new hockey stick provider for on-ice use, the league confirmed to Sportico. Only six companies currently outfit every NHLer according to geargeek.com, with three—Bauer, CCM and Warrior—owning nearly 98 percent of the market.

Penguins assistant coach Mark Recchi remembers the puzzling looks on his players’ faces when he first brought a TOVI stick onto the ice at the beginning of this season. With a pattern of diamond-cut holes in the blade, the stick looks more like floor hockey equipment than NHL gear, but Recchi says that you don’t notice the unique design while holding the stick yourself. He was, however, struck by the puck control the stick helped him achieve.

Fellow former NHLer Frank Simonetti said TOVI’s stick felt more like the wooden sticks he used in the 1980s than anything else he’s tried since. The first hockey sticks were hand carved from a single piece of wood, the material of choice for decades. Wooden sticks with foam cores then offered a lighter option, followed by durable aluminum builds. In the 2000s, composite sticks largely made from graphite and carbon fiber slowly took over.

In addition to the enhanced feel for the puck, Recchi and Simonetti both cited not needing to put tape on the patented TOVI blade as another benefit. Other reviewers have pointed to the stick’s durability as a selling point.

The stick is the result of nearly a decade’s worth of work by Boston-area inventors Tovi Avnery and Scott Heitmann. They started by using Heitmann’s experience crafting military equipment with carbon fiber to try building a safer football helmet before determining that his material was too hard for that application. Baseball bats were also ruled out for similar reasons.

When the designers turned their attention to hockey sticks, they found that solid carbon fiber could replace the need for a blade core but would produce too heavy of a blade. Thus the idea for the perforations. Later aerodynamic testing found that the gridcut pattern could also reduce drag when shooting.

The company started with capital from its three founders, Avnery, Heitmann and Rich Fucillo. It is currently seeking a round of investment to expand its manufacturing and sales infrastructure. Shark Tank alum Aaron Krause (of Scrub Daddy fame) has also come on as an investor at an undisclosed valuation as well as TOVI’s branding lead. His first move was to rename what had been Carbon Sports after Avnery. The company’s three stick models currently retail between $200 and $300.

While many NHL players have stick contracts with the three major manufacturers, agent Scott Bartlett said it’s not uncommon for other manufacturers to send players custom-made sticks in the offseason in the hopes of wooing them. “Guys are looking for every bit of performance improvement they can get,” he said.

In recent years, those innovations have included custom made skates using laser-scanning technology, as well as heated skate blades, though those failed to catch on.

“Pretty much every player is experimental,” Recchi said, before singling out one player who might take a particular interest in trying TOVI’s product, center Evgeni Malkin. “Malkin is the most experimental. I’m sure he’ll be grabbing this once we get going.”

Advanced hockey stick design delivers optimal performance

Design Results:

• Fiber architecture enables precise location of dual kickpoints, providing predictable stick bending moments for two common hockey shots.
• Custom nanotoughened epoxy resin reduces crack propagation and increases stick fatigue-resistance.
• Tapered design of the shaft’s rectangular cross-section enables a jointless transition to the blade in a one-piece construction.
   

At one time, a hockey stick was like Henry Ford’s all-black Model T: you could get any size or style of stick you wanted, as long as it was wood. The introduction of composite sticks in 1999, however, enabled designers to build sticks 35 percent lighter than their wood predecessors and perfect once impossible stick designs that have since changed the game. A notable example is the VAPOR APX stick from Bauer Hockey Inc. (Greenland, N.H.). The stick (launched in fall 2011) tops the VAPOR product line, which is one of Bauer’s two lines for the retail market. It differs from the company’s more conventional TOTALONE stick (launched a year earlier in the company’s SUPREME product line) in terms of blade structure, shaft shape and its stiffness profile, or what hockey players call the kickpoint.

The kickpoint is the point on the shaft at which the stick flexes during the act of shooting the puck. Unlike other composite sports equipment — such as tennis rackets and golf clubs, which are swung in a simple pendulum motion and (ideally) contact only the ball — a hockey stick is swung in a more forceful, linear motion (see photos) and the blade hits the ice, intentionally, some distance behind the puck. Here, the kickpoint allows the stick to bend, thus storing and transferring a significant amount of energy. The stick reaches its maximum bending moment before the blade hits the puck. When it contacts the puck, the stored energy is released during the follow through. In general, a composite hockey stick must be able to withstand a nonlinear dynamic load of 1,000N to 1,200N for 1.2 seconds without fatigue in the fiber matrix during 1,000-plus cycles.

Like the majority of retail sticks, the TOTALONE is designed with a single kickpoint near the middle of the shaft. The APX, however, features two kickpoints, a performance feature Bauer markets as Intelli-Sense Shot Technology. Kickpoints are designed into composite sticks by making the shaft stiffer in some areas (by adding layers of reinforcing material in strategic locations) and more flexible in other areas (by using less material or by reorienting the fibers). The stiffest region of the VAPOR APX is about 18 inches/457 mm above the stick’s heel, with more flexible regions below and above, yielding two areas of flex: one about 10 inches/254 mm below the point of maximum stiffness and the other the same distance above it.

Adam Gans, Bauer’s director of product development, explains that the dual-kickpoint design accommodates hockey’s most common shots — the slap shot and the wrist shot. During a slap shot, a heavier load is applied to the shaft and the low hand position is below the stiffest section to take advantage of the kickpoint nearest the ice. The distance and, therefore, the time between initial contact with the ice and contact with the puck is short, resulting in a quicker shot. During a wrist shot, the low hand is positioned above the upper kickpoint, so the shaft bends in two places, maximizing energy storage. Thus, the player can transfer more energy to the puck.

Fiber architecture

A standard hockey stick shaft has a hollow, rectangular cross-section. The cross-sectional dimensions of the upper portion of the VAPOR APX are 0.76 inch by 1.175 inches (1.93 cm by 2.98 cm), with radiused corners (radii of 0.21 inch/5.5 mm) on each of the shaft’s four edges. The VAPOR APX stick’s standard length is 60 inches/1. 52m. A long and complex series of tapers are built into the lower region of the stick to connect the wider shaft to the thinner blade.

Gans explains that, beyond weight, there are three major stick design criteria. First, the materials must be able to store and release energy quickly, which is why certain grades of carbon fiber are advantageous. Second, the shaft must have a stiffness profile that complements a player’s biomechanics to optimize shooting capacity. Third, the blade must damp  impact well enough to ensure that the puck will stay on the blade while the player is shooting or receiving a pass, yet it also must provide enough sensation to allow the player to feel where the puck is on the blade.

The VAPOR APX comprises four main components: the stick’s shaft core, the shaft’s outer layer, the shaft taper and the blade. The shaft is built up around a proprietary expandable mandrel. The shaft core features 13 to 15 layers of material, 4 inches to 60 inches (102 mm to 1,524 mm) in length, laid down in an alternating sequence of orientations. The layers are high-strength, standard-modulus, low-FAW (fiber aerial weight) unidirectional (UD) 15K carbon fiber prepreg tape supplied by Mitsubishi (Toyohashi, Japan). Designers specify that material should be layered to a particular thickness.

“The more layers you have, the more you can distribute the orientation of the fibers,” says Gans. The orientation sequence in a core cross-section follows a pattern (e.g., 30°/45°/30°/19°/0°/30°), and the pattern varies depending on the area of the stick and its specified stiffness profile. “When you have a good distribution of fiber angles, you have a better distribution of stress,” explains Gans, noting that more layers of 0° fiber increase linear stiffness; more layers of 45° fiber increase torsional stiffness; and more layers of 90° fiber increase resistance to buckling. The VAPOR APX architecture is designed to impart optimal resistance to fatigue. Although the dual-kickpoint architecture is proprietary, Gans reports that the company “uses localized inserts with specific fiber orientations to achieve the high-modulus zone at 18 inches [457 mm] from the stick’s heel. ”

For the VAPOR APX, Bauer collaborated with Mitsubishi on the development of eLASTech, a toughened epoxy-based resin system that incorporates carbon nanotubes and thermoplastic nanoparticles. Gans says the formulation impedes crack propagation and resists interlaminar shear better than toughened resins that feature other additives, such as liquid rubber. “When you get a load that is parallel to the laminate, it’s the epoxy that’s going to take that load,” he explains, “so it’s important to have a toughened resin that resists fatigue and increases the longevity of the stick.”

The shaft’s outer layer is a single ply of FAW100 TeXtreme Spread Tow fabric, which is supplied to Mitsubishi by manufacturer Oxeon AB (Borås, Sweden), then impregnated by Mitsubishi with eLASTech resin for the core’s UD layers. Oxeon’s spread-tow fabrics are produced by weaving spread-tow tapes. Two of the fabric’s main benefits are reduced weight and extremely low crimp that increases mechanical properties compared to a standard 3K woven fabric. Another advantage is greater compatibility with the inner prepreg layers. “TeXtreme fibers, which are relatively flat, are adjacent to the UD layers, which are absolutely flat,” Gans observes. “The mechanical commonality creates less stress, so there is less likelihood of shearing between the two layers.”

Gans claims that Bauer is the only hockey stick manufacturer that uses a “mono-comp” molding process in which the VAPOR APX and SUPREME TOTALONE sticks are each molded in one piece in a single shot. The process is more complicated than molding a blade and a shaft separately, but it eliminates the weight penalty paid in the more common two-part process where the shaft and the blade are adhesively bonded at a mortise-and-tenon joint, which adds weight where it is least desired, skewing the kickpoint and adding unwanted stiffness at the attachment point.

The design of the shaft’s taper facilitates the dual-kickpoint action and allows the manufacture of an integrated structure in a single shot. Below the 18-inch point of maximum stiffness, the rectangular cross-section of the shaft begins to taper in two directions: from side to side (the narrower cross-sectional width) and from front to back. Gans emphasizes that the goal is to make the taper thin enough to provide the shooter with the desired bend and whipping action, but not make it so thin that the transitional region is subject to high forces of torque, which can cause the stick to twist and result in loss of shot precision. He explains that the shaft-to-blade transition zone was carefully tuned by modifying the taper’s layup and UD fiber orientations in the area, and by optimizing the geometry.

The shaft core terminates at the stick’s heel, where it mates with the blade core. Here, Bauer uses two types of expandable foams. A low-density foam is used in the portion of the blade that receives fewer impacts, that is, at the intersection of the shaft and the heel of the blade. A syntactic epoxy foam with high shear strength, developed by Bauer in-house, is used in the blade body. The blade’s outer layer is formed from the same spread-tow fabric prepreg used for the shaft’s outer layer. The VAPOR APX stick is sold with eight blade pattern options, each of which has its own individual length, height and curvature. Most blades are 8 inches to 9 inches long (20.3 cm to 22.9 cm) and 2.5 inches (6.36 cm) high, with a thickness that varies from 0.350 inch (8.8 mm) at the heel to 0.150 inch (3.8 mm) at the toe.

Bauer “tech packs” — which include the detailed layup sequence of the inner UD prepreg layers, woven outer layer and blade core materials — are assembled in-house at the company’s R&D facility in St. Jerome, Quebec, Canada. The combination of narrow rectangular shapes (and corner radii) and multiple tapers presents a manufacturing challenge that is met by precise control of preform assembly and molding conditions to prevent bridging and voids in the laminate. Tech packs are shipped to China, where they are compression molded using Bauer’s proprietary molding technology, which is designed to optimize compaction of the core’s laminate walls. Postmold operations include sanding then applying a clearcoat, decals and a final layer of clearcoat. The stick is then ready to put the puck in the net.

In addition to its retail product lines, Bauer designs custom sticks for NHL athletes and other elite players. Knowledge gained in custom stick design informs the company’s retail product strategies. This spring saw the launch of a third Bauer product line, headlined by the NEXUS 1000, an all carbon-fiber stick with a “Tru-Mid” kickpoint that has enjoyed great success in pro sticks for several years on NHL ice.

90,000 Hydrocarbon fiber, carbon fiber, production of polymer materials and carbon fiber, carbon fiber price

Carbon fiber – a material consisting of thin filaments with a diameter of 3 to 15 microns, formed mainly by carbon atoms. Carbon atoms are combined into microscopic crystals aligned parallel to each other. The alignment of the crystals gives the fiber greater tensile strength. Carbon fibers are characterized by high tensile strength, low specific gravity, low coefficient of thermal expansion and chemical inertness.

The production of carbon fiber in Russia is carried out by the Composite-Fiber LLC company, which is part of the Composite holding

Carbon fiber is the basis for the production of carbon plastics (or carbon, carbon plastics, from “carbon”, “carbone” – carbon).CFRPs are polymer composite materials made of interwoven carbon fiber strands located in a matrix of polymer (usually epoxy) resins.

Carbon composite materials are characterized by high strength, rigidity and low weight, often stronger than steel, but much lighter.

Why is the price of carbon fiber so high?

High energy consumption is the main reason for the high cost of carbon fiber.However, this is more than offset by an impressive result. It’s hard to believe that it all started with “soft and fluffy” material contained in rather mundane things and known not only to employees of chemical laboratories. White fibers – so-called polyacrylonitrile copolymers – are widely used in the textile industry. They are a part of dress, costume and knitted fabrics, carpets, tarpaulins, upholstery and filter materials. In other words, polyacrylonitrile copolymers are present wherever acrylic is mentioned on the accompanying label.Some of them “serve” as plastics. The most common among these is ABS plastic. So it turns out that carbon has a lot of “cousins”.
Carbon filament has impressive tensile strength, but its ability to “take impact” on bending “let us down”. Therefore, for equal strength of products, it is preferable to use fabric. The fibers organized in a certain order “help” each other to cope with the load. Unidirectional tapes lack this advantage.However, by setting different orientations of the layers, it is possible to achieve the desired strength in the desired direction, significantly save on the mass of the part and not unnecessarily reinforce non-fundamental places.

What is carbon fabric?

For the manufacture of carbon parts, both just carbon fiber with randomly arranged threads filling the entire volume of the material, and fabric (Carbon Fabric) are used. There are dozens of types of weaving. The most common are Plain, Twill, Satin.Sometimes weaving is conditional – a ribbon of longitudinally located fibers is “stuck” with rare transverse stitches only in order not to crumble.
The density of the fabric, or specific gravity, expressed in g / m2, in addition to the type of weaving, depends on the thickness of the fiber, which is determined by the number of carbons. This characteristic is a multiple of one thousand. So, the abbreviation 1K means a thousand strands in a fiber. Plain and Twill weaving fabrics with a density of 150–600 g / m2, with a fiber thickness of 1K, 2 are used most often in motorsport and tuning.5K, 3K, 6K, 12K and 24K. 12K fabric is also widely used in military products (hulls and heads of ballistic missiles, propeller blades of helicopters and submarines, etc.), that is, where parts are subjected to colossal loads.

Is there a colored carbon? Does yellow carbon exist?

Often from manufacturers of tuning parts and, as a result, from customers, you can hear about “silver” or “colored” carbon. “Silver” or “aluminum” color is just paint or metallized coating on glass fabric.And it is inappropriate to call such material carbon – it is fiberglass. It is gratifying that new ideas continue to appear in this area, but in terms of characteristics, glass cannot be compared with carbon carbon. Colored fabrics are most often made of Kevlar. Although some manufacturers use fiberglass here as well; even dyed viscose and polyethylene are found. When trying to save money, replacing Kevlar with the mentioned polymer threads, the adhesion of such a product with resins deteriorates. There can be no question of any durability of products with such fabrics.Note that Kevlar, Nomex and Twaron are proprietary American polymer brands. Their scientific name is “aramids”. These are relatives of nylons and nylon. Russia has its own analogues – SVM, Rusar, Terlon SB and Armos. But, as often happens, the most “promoted” name – “Kevlar” – has become a household name for all materials.

What is Kevlar and what are its properties?

Kevlar is inferior to carbon fiber in terms of weight, strength and temperature properties.The ability of Kevlar to perceive bending loads is significantly higher. This is the reason for the appearance of hybrid fabrics, in which carbon and Kevlar are contained approximately equally. Parts with carbon aramid fibers absorb elastic deformation better than carbon fiber products. However, they also have disadvantages. Carbon-Kevlar composite is less durable. In addition, it is heavier and “afraid” of water. Aramid fibers tend to absorb moisture, which affects both themselves and most resins. The point is not only that “epoxy” is gradually destroyed by a water-salt solution at a chemical level.Heating and cooling, and in winter freezing altogether, the water mechanically loosens the material of the part from the inside. And two more comments. Kevlar decomposes when exposed to ultraviolet light, and the molded material in the resin loses some of its wonderful qualities. High tear and cut resistance distinguishes Kevlar fabric only when it is dry. Therefore, aramids show their best properties in other areas. Mats made from several layers of such materials are the main component for the production of light body armor and other safety equipment.Kevlar threads are used to weave thin and strong ship ropes, make a cord in tires, use in drive belts of mechanisms and seat belts on cars.

Can you glue the part with carbon?

An irresistible desire to have black-and-black or black-colored checkered parts in your car led to the emergence of outlandish carbon substitutes. Tuning salons glue the wooden and plastic panels of the salons with carbon cloth and fill them with countless layers of varnish, with intermediate sanding.Each detail takes kilograms of materials and a lot of working time. One can bow before the diligence of the masters, but this path does not lead anywhere. “Decorations” made in a similar technique sometimes do not withstand temperature changes. Over time, a web of cracks appears, the details delaminate. New parts are reluctant to fit into their regular places due to the large thickness of the varnish layer.

How are carbon and / or composite products made?

The technology for the production of real carbon products is based on the characteristics of the resins used.There are a great many compounds, as resins are correctly called. Cold cured polyester and epoxy resins are most common among fiberglass body kit manufacturers, but they fail to fully exploit the full benefits of carbon fiber. First of all, due to the weak strength of these bonding compounds. If we add to this the poor resistance to high temperatures and ultraviolet rays, then the prospect of using most common brands is very doubtful.A carbon fiber hood made of such materials will have time to turn yellow and lose its shape during one hot summer month. By the way, “hot” resins do not like ultraviolet light either, therefore, for safety, the parts should be covered with at least a transparent automobile varnish.

Cold hardening compounds.

“Cold” technologies of small-scale production of unimportant parts do not allow to unfold, as they have other serious disadvantages. Vacuum methods for the manufacture of composites (resin is fed into a closed matrix, from which air is evacuated) require long-term preparation of the tooling. Add to this the mixing of the resin components, which “kills” a lot of time, which also does not contribute to productivity. It’s not worth talking about manual gluing at all. The method of spraying chopped fiber into a matrix does not allow the use of fabrics. Actually, everything is identical to fiberglass production. It’s just that coal is used instead of glass. Even the most automated of the processes, which also allows working with high-temperature resins (winding method), is suitable for a narrow list of closed-section parts and requires very expensive equipment.

Hot cure epoxy resins are more durable, allowing for the full manifestation of carbon qualities. For some “hot” resins, the polymerization mechanism at “room” temperature starts very slowly. What, in fact, is the basis of the so-called prepreg technology, which involves the application of the finished resin to carbon fiber or carbon fiber long before the molding process. The prepared materials are just waiting in the wings in the warehouses.

Depending on the brand of resin, the liquid time usually lasts from several hours to several weeks.To extend pot life, prepared prepregs are sometimes stored in refrigerated chambers. Some brands of resins “live” for years in finished form. Before adding the hardener, the resins are heated to 50-60 C, after which, after mixing, they are applied using special equipment to the fabric. Then the fabric is laid with plastic wrap, rolled up and cooled to 20-25 C. In this form, the material will be stored for a very long time. Moreover, the cooled resin dries up and becomes practically invisible on the surface of the fabric.Directly during the manufacture of the part, the heated binder becomes liquid like water, due to which it spreads, filling the entire volume of the working form and the polymerization process is accelerated.

Hot curing compounds.

“Hot” compounds are great variety, while each has its own temperature and time modes of curing. Typically, the higher the required thermometer reading during the molding process, the stronger and more heat-resistant the finished product. Based on the capabilities of the existing equipment and the required characteristics of the final product, it is possible not only to select the appropriate resins, but to make them to order.Some domestic manufacturing plants offer this service. Naturally, not free.

Prepregs are perfect for the production of carbon in autoclaves. Before loading into the working chamber, the required amount of material is carefully placed in the matrix and covered with a vacuum bag on special spacers. Correct positioning of all components is very important, otherwise unwanted folds caused by pressure cannot be avoided. It will be impossible to correct the error later.If the preparation was carried out with a liquid binder, it would be a real test for the nervous system of workers with unclear prospects for the success of the operation.

The processes taking place inside the installation are unpretentious. The high temperature melts the binder and “turns on” the polymerization, the vacuum bag removes air and excess resin, and the increased pressure in the chamber presses all layers of the fabric against the matrix. And everything happens at the same time.

On the one hand, there are some advantages. The strength of such CFRP is practically maximum, objects of the most intricate shapes are made in one “sitting”.The dies themselves are not monumental as the pressure is evenly distributed in all directions and does not disturb the geometry of the rig. Which means fast preparation of new projects. On the other hand, heating up to several hundred degrees and pressure, sometimes reaching 20 atm., Make the autoclave a very expensive construction. Depending on its size, equipment prices range from several hundred thousand to several million dollars. Add to this the merciless consumption of electricity and the labor intensity of the production cycle.The result is a high production cost. There are, however, more expensive and more complex technologies, whose results are even more impressive. Carbon-carbon composite materials (CCCM) in brake discs on Formula 1 race cars and in rocket engine nozzles withstand monstrous loads at operating temperatures reaching 3000 C. The operation is somewhat similar to the production of carbon fiber itself, only it takes place at a pressure of 100 atmospheres.Yes, big sports and the military-space sphere of activity are capable of consuming piece things at exorbitant prices. For tuning and, moreover, for serial production, such a price-quality ratio is unacceptable.

If a solution has been found, it looks so simple that one wonders: “What prevented you from thinking of it earlier?”. Nevertheless, the idea to separate the processes taking place in the autoclave came up after years of searching. This is how the technology appeared and began to gain momentum, making carbon hot-forming similar to stamping.The prepreg is prepared in the form of a sandwich. After applying the resin, the fabric is covered on both sides with either polyethylene or a more heat-resistant film. The “sandwich” is passed between two shafts pressed against each other. This removes excess tar and unwanted air, much like spinning laundry in 1960s washing machines. The prepreg is pressed into the matrix with a punch, which is fixed with threaded connections. Further, the entire structure is placed in a heating cabinet.

Tuning firms produce matrices from the same carbon fiber and even durable alabaster grades.Gypsum working forms, however, are short-lived, but they are quite capable of a couple of products. More “advanced” dies are made of metal and are sometimes equipped with built-in heating elements. They are optimal in series production. By the way, the method is also suitable for some parts of a closed section. In this case, the lightweight foam punch remains inside the finished product. The Mitsubishi Evo wing is an example of this kind.

Mechanical efforts make you think about the strength of the tooling, and the matrix-punch system requires either 3D modeling or a top-class modeler.But this, nevertheless, is hundreds of times cheaper than the technology with an autoclave.

Microstructure of carbon fiber and carbon fiber reinforced plastic

Microstructure of Carbon Fiber and Carbon Reinforced Plastic

N. I. Baurova, Wei Hao, Ouyang Xiao

August 2013

This study was carried out to study the microstructure of various types of carbon fiber (Russian-made carbon fiber – https: // dipchel.ru / store / uglerodnoe-volokno /). A comparison was made between carbonized and graphitized fibers. Conclusions were drawn about the results of structural studies. The damage was found to vary from various dirt and damage to the monofilaments. The effect of contamination of the monofilament was determined.

Key Words: Cold curing of epoxy matrix; Carbon fiber; Carbon fiber reinforced plastic; Microstructure

1. Introduction
Carbon fibers (HC), as well as carbon ribbons and fabrics, have been used for a long time in the power supply circuits of various types of aircraft, both in Russia and in foreign countries, for the production of load-bearing panels for wings, empennage and fuselage; for the production of coatings from three-layer panels of various types of antennas operating in space; turbine blades, nozzle blocks, nose cones and many other structures. Carbon fibers are widely used in the manufacture of various heating elements.
Carbon fibers are a bundle of monofilaments, the number of which depends on the grade of carbon fibers, and can vary over a very wide range, from several thousand to tens of thousands of pieces. Each monofilament is a nanoporous strong substance that has unique electrophysical properties, which opens up new areas of their application, for example, as sensor sensors in the diagnosis of structures in real time [1].
Carbon fibers obtained by heating cellulose (poliakrilonitrilny and other types) fibers. This is a complex process that takes place in several stages. At the first stage, oxidation occurs at a temperature of 200 90 438 0 90 439 C or 325 90 438 0 90 439 C, at which the main loss of weight and shrinkage of the fiber occurs. In the second stage, carbonization is carried out at a temperature of 1000 ^{0 90 439 C or 1500 90 438 0 90 439 C, then at a temperature of 2500 90 438 0 90 439 C a multifunctional fiber is obtained and at 2800 90 438 0 90 439 C a graphite fiber is obtained. Depending on the stage in which the production process was interrupted, either carbonized fibers with different high strengths, or graphitized fibers with a high modulus of elasticity. Simply, the model of the structure of carbon fiber can be represented in the form of successively alternating blocks of crystallites, which connect amorphous areas to each other [2].}

2. Experimental Process
In this work, structural studies of four different carbon fibers are carried out using a scanning and electron microscope company Phenom.

3. Results and discussion

3.1. Carbon Mono-Fibers
The structure of carbon fibers is formed during carbonization and the degree of graphitization as a result of physical and chemical processes. The process of formation of a nanostructure of carbon fiber consists of two stages: at the first stage of the formation of macromolecules of nanostructured formations — microfibrilla occurs. At the second stage, as the temperature rises, the macromolecule gradually turns from twisted into a linear one and the diameter of the monofilament increases. This is because gradually all functional groups present in the structure are decomposed with the formation of amorphous carbon chains. There is a gap between the monofilaments, which inevitably arises due to the shrinkage of the carbon fiber, which occurs at all stages of its oxidation (see Fig. 1). As the temperature rises, the number of covalent bonds with which a number of microfibrilla is gradually connected increases.
Thus, the structure of graphitized carbon fibers is anisotropic and represents crystallites thickened among them and amorphous regions consisting of carbon atoms (see.rice. 1), these sites are of dark and light colors, respectively. For cars made of carbon fiber, used in the diagnosis of nanostructured axial and annular structure in relation to the characteristic of the fiber axis. In the central regions of the fibers, they are characterized by the highest stress concentration. There are areas with a radial orientation along the edges of the fiber. Heat-resistant inclusions differ significantly from the basic structure of the fiber.

Figure 1. Carbon fiber mono-filament structure: (a) Elur; (b), (c) Culon; (d) LU; (e) UKN-P; (f) UKN-2-500.

As a result of the studies, it was found that carbonized carbon fibers contain a large amount of impurities, which are not completely removed coke particles from the organic polymer (Fig. 2). These impurities have a significant effect on the electrical properties of carbon fibers, and for this reason carbonized fibers cannot be used as sensors for diagnosing metal structures [3].

Graphitized carbon fibers contain fewer impurities and therefore have more stable electrical properties.In the longitudinal direction, that is, parallel to the fiber axis, carbon monofibers have a well-focused and similar structure, which is associated with the peculiarities of the arrangement of the graphite layers.

The diameters of mono-filaments of carbon fibers in the same batch are close to each other and make about 10.5 microns. The exact size of a mono-filament of carbon fibers is determined directly in microplastics.

Rice.2. The emergence of mono-filaments in graphitized (a) and carburized (b) fibers.

3.2. Carbon in Mono-Fiber Reinforced Composites

For further research, using UKN-2500 carbon fibers and epoxy resin binders based on the epoxidane field and an ammonium hardener, samples of microplastics, which after complete cold curing – a systematic impact process at 20 90 438 0 90 439 C for 24 hours were tested for rupture and destruction of the surface, after which they were examined with an electron microscope.Determination of the nature of destruction, on the basis of which it would be possible to predict the durability, served as the purpose of these studies.

The carried out structural analysis showed (Fig. 3) that the adhesion nature of destruction takes place, ie, the rupture occurs exactly at the surface of the interphase boundary in the polymer matrix — carbon fiber. The nature of the destruction of elastic and black objects in the photo indicate the places where the monofilaments were dug along with the obligatory ones.

Rice.3. Photo of the destruction of the surface of carbon fiber-reinforced plastic.

Based on the results of structural studies of carbon fibers, it can be assumed that contamination on the surface of the monofilament, representing coke particles, is completely not removed during graphitization, does not allow to obtain a strong adhesion between the fiber and the polymer matrix, and peeling from the fiber occurs under loads in the matrix.

As a recommendation for increasing the size of adhesive strength, it is possible to recommend using a special finishing coat, which is necessary when processing the surface of carbon fibers before applying a layer.

Like other recommendations that will also increase the strength of the adhesive interaction of carbon fibers and epoxy binders, it is necessary to use planed wood in carbon fibers; bonded with a lower viscosity, which will significantly reduce the thickness of the bonding layer between two rows of mono-threads. There are two different ways to reduce viscosity. The first is the use of a solvent, the second is mandatory heating before impregnation.In the first method, carbon of the reinforced plastic with a minimum thickness of the bonding layer will be obtained, however, the process takes additional time, which will be spent on volatilization of the solvent during the curing process. The second method will make it possible to obtain a composite profile, however, the thickness of the bonding layer will be higher than when using other technology.

The resulting surface structures show that this binding does not have relaxation properties at submicroscopic levels, and most likely this leads to multiple cracking.

Further, at the microlevel, there is a rapid formation of areas where the accumulation of defects occurs, which leads to the fact that, at a certain concentration of defects, the formation of a main crack occurs, which, as a rule, develops at a high rate in brittle materials and will occur rapidly, and during development this crack is capable of further grab the next monofilaments.

4. Conclusion

Structural studies of carbon fibers and microplastics have shown on their basis that the used carbon fibers of the UKN-2500 grade have a large number of initial defects in the form of contamination along their entire length, which as a result leads to brittle and adhesive destruction of the carbon fiber reinforced plastic.The use of these carbon fibers in the production of critical parts from carbon reinforced plastic will require additional measures, which allows increasing the size of the adhesive strength in the interfacial zone.
