Carbon Fiber

Weaving carbon fibers




What's it made of?

A series of thin fibers mostly composed of carbon atoms. These atoms are bonded with microscopic crystals, aligned in a parallel direction to give the fiber its strength. The fibers are then woven and molded into a fabric or composite form. Carbon fiber has a high tensile strength that one could drop several tons on the fabric and it would resist wear and tear. The material is widely used in aerospace, civil engineering, military, speed bikes and race cars.

Fiber Reinforced Polymers:

Defined: They are composite materials with a polymer matrix of reinforced fibers. These fibers are usually composed of fiberglass, carbon, or aramid. The Polymer a plastic made up of epoxy, vinlester, or thermal polyester. This material is commonly used in aerospace, marine, industry, and architecture.



Polymers are used in just about every by-product, manufactured and processed through chemically enhancing the component to develop a new substrate material. Smart Polymers are those materials that consist of polymers that dramatically react to their environment. Studies in biological makeup help inform scientists to develop materials that change with specific properties. Such properties include the development, controllability, and chemical formulations to alter the chemical makeup. Smart polymer materials are constantly being investigated in biotechnology for potential applications such as medical, industrial, commercial, and architecture.








The pultrusion process accommodates a variety of reinforcement and matrix combinations.
Our standard material is glass fibre reinforced polyester. Other combinations are available on order.

Classification

A.1.1

There are several different types of polymers with many properties ranging from chemical to organic structure.


Material Type / Grade





   Material Type / Grade       
   Your choices are...
 
    
 
   Monomer / Intermediate
 
     Resin component, monomer, intermediate, oligomer, pre-polymer or other building blocks and raw materials for plastic or elastomer polymer production.
 
   Binder / Base Polymer
 
     Base polymers or binders, binding agents and film formers are starting components mixed with other fillers and additives by compounders to produce plastic resins, elastomers, adhesives, sealants, coatings, paints or other polymer based products.

Binders are also adhesives used to hold together particulates such as polyvinyl alcohol, waxes, phenolics or other compounds.  They are used in fabricating powder metal compacts, ceramic binders, fuel pellets, brake pads, particle board, and pharmaceuticals pills or preparations.
 
   Composite Material
 
     Material filled with a strengthening phase, reinforcement fibers, toughening phase or other specialty fillers that provide unique properties.
 
   Thermoplastic Material
 
     Thermoplastics can be repeatedly softened by heat and then hardened, or set by cooling, which allows parts to be injection molded or thermoformed and scrap to be reprocessed.
 
   Thermoset / Crosslinked Material
 
     Thermoset plastics and thermoset resins are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins generally have higher resistance to heat compared to thermoplastics, but melting cannot reprocess them.
 
   Semi-finished / Shaped Stock (Bar, Sheet, etc.)
 
     Semi-finished or shaped stock forms of plastics or elastomers include bar, sheet, film, profiles, or other shapes suited for part fabrication by machining, forming, welding, mechanical assembly or other processes.
 
   Fabricated Shape / Part (Molded, Cast)
 
     Polymers or elastomers fabricated into finished shapes or parts using molding, casting, extrusion, pultrusion, machining, thermal forming, plastic welding, blow molding, rapid prototyping techniques, grinding and/or other specialized processes. The exact dimensions and tolerances of the finished molded or cast parts are typically made-to-print based on the OEMs requirements and the supplier's in-house capabilities.
 
   Resin / Compound Raw Material (Pellets, Liquid)
 
     Polymer material is a resin or compounded raw or unfinished material such as pellets, liquids, bulk molding compounds, or other forms.
 
   Electrical / Electronic Material
 
     Polymers, elastomers or resins specialized for electronics applications such as thermal interface materials, electrical insulation, potting or encapsulating compounds, conductive adhesives and dielectric sealants.
 
   Optical Grade / Material
 
     Polymers or elastomers designed for optical or photonics applications such as transparent polycarbonate or acrylic lens materials.
 
   Self-lubricated / Bearing Grade
 
     Compounded polymers or elastomers use solid lubricant fillers such as graphite, molybdenum disulfide, polytetrafluoroethylene (PTFE), or boron nitride.
 
   Specialty / Other
 
     Other unlisted, specialized and proprietary polymers, resins, monomers or intermediates. These materials are based on a unique chemical or polymer systems, novel curing technologies or have properties tailored for specific applications.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Cure Type / Technology




   Cure Type / Technology       
   Your choices are...
 
    
 
   Air Setting / Film Drying
 
     Air setting or film drying materials form a bond or "harden" by evaporating water or an organic solvent. Inorganic binders or cements are sometimes air setting; refractory type may develop strong bonds after firing.  Pastes and gum adhesives are often film drying.
 
   Anaerobic
 
     Anaerobic adhesives cure in the absence of air or oxygen.
 
   Thermoplastic / Hot Melt
 
     Thermoplastics can be repeatedly softened by heat and then hardened, or set by cooling, which allows parts to be injection molded or thermoformed and scrap to be reprocessed.

Thermoplastic or hot melt adhesives can be repeatedly softened by heat and then hardened, or set by cooling, which allows parts to be removed or repositioned during assembly. Hot melt adhesives are typically solvent-free thermoplastics that melt or drop in viscosity above 180°F, and then rapidly set upon cooling. They are used in a variety of manufacturing processes, including bookbinding, woodworking, construction, product assembly, and box and carton heat sealing.  Hot melt adhesive technology stemmed from the previous use of molten wax for bonding.

Thermoplastic systems were introduced to satisfy performance needs. Typically, a pure hot melt system will not have the heat resistance of two-part, catalyst or thermoset adhesives.  Hybrid hot melt systems are available that have exhibit a degree of reactive curing.  Polyethylenes, polyamides and ethylene-vinyl acetates are common types of hot melt adhesives. Heat activated adhesives become sticky or tacky when warmed, and are used in contact or PSA type applications.
 
   Thermosetting (Crosslinking/ Vulcanizing)
 
     Thermoset plastics and thermoset resins are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins generally have higher resistance to heat when compared to thermoplastics, but they cannot be melted down and reprocessed.

Thermoset adhesives are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins do not melt and flow when heated, but they may soften.  Phenolic, melamine and urea formaldehyde resins are thermosetting adhesives that offer strong bonds and good resistance to high temperatures.  Vulcanization is a thermosetting reaction involving the use of heat and/or pressure in conjunction with a vulcanizing agent, resulting in greatly increased strength, stability and elasticity in rubber-like materials. RTV silicone rubbers are room temperature vulcanizing materials.  The vulcanizing agent is a crosslinking compound or catalyst.  Sulfur is the traditional vulcanizing agent used with natural rubber. Silicones use moisture, acetic acid and other compounds as curing agents.
 
   Room Temp. Cure / Vulcanizing
 
     Polymer resin or compounds that either cure or vulcanize at room temperature. Vulcanization is a thermosetting reaction involving the use of heat and/or pressure in conjunction with a vulcanizing agent, resulting in greatly increased strength, stability and elasticity in rubber-like materials.  The vulcanizing agent is a crosslinking compound or catalyst.  Silicones use moisture, acetic acid and other compounds as curing or vulcanizing agents.
 
   Contact / Pressure Sensitive (PSA)
 
     Pressure sensitive adhesives adhere to most surfaces with very slight pressure and they retain their tackiness. They are available in solvent and latex or water based forms. Pressure sensitive adhesives are often based on non-crosslinked rubber adhesives, acrylics or polyurethanes.  They form viscoelastic bonds that are aggressively and permanently tacky, and adhere without the need of more than finger or hand pressure.
 
   UV / Radiation Cured (also EB, Light)
 
     UV or radiation cured adhesives use ultraviolet light, visible light or electron bean irradiation to initiate curing, which allows a permanent bond without heating or excessive heat generation. One disadvantage of UV curing adhesives is the requirement that one substrate is UV transparent.  Some UV resin systems employ a secondary curing mechanism to complete curing of adhesive regions shielded from the UV light.  EB curable adhesives use electron beam radiation to cure or initiate curing.  The electron beam can penetrate through material that is opaque to UV light.
 
   Reactive / Moisture Cured
 
     Reactive resins are single component adhesives that are applied in the same way as hot melt adhesives. The resins react with moisture to crosslink and polymerize resulting in a cured material. Polyurethane reactives (PUR) are examples of this type of technology. Certain silicones and cyanoacrylates also use a reaction with moisture or water to cure the adhesive or sealant.
 
   Single Component System
 
     Single component adhesives or sealant systems consist of one resin that hardens by reaction with surface moisture, a surface applied activator-primer, or through the application of heat.
 
   Two Component System
 
     Two or multi-component adhesive or sealant systems consist of two or more resins or a resin and a hardener, crosslinker, activator or catalyst that when combined react and cure into a polymerized compound or bond. Two component systems are mixed and then applied.
 
   Specialty / Other
 
     Other unlisted, specialty, proprietary technology or cure type.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Material System




   Chemical / Polymer System Type       
   Your choices are...
 
    
 
   ABS
 
     Acrylonitrile-butadiene-styrene (ABS) is a hard, rigid, thermoplastic polymer. It provides good chemical and creep resistance along with dimensional stability. ABS is used in many industries and in a wide array of applications. It is generally inexpensive, but prone to crack under stress. Common trade names include Cycolac® (GE Plastics), Lustran® (Bayer) and Novodur® (Bayer).
 
   Acetal / Polyoxymethylene (POM)
 
     Polyacetal or polyoxymethylene (POM) provides a higher strength material compared to polyethylene-type polymers; however, polyacetal materials are susceptible to oxidation at elevated temperatures. DuPont’s Delrin® is a common polyacetal engineering resin that is also used to mold plastic parts.
 
   Acrylic / Polyacrylate
 
     Acrylic polymers are formed by polymerizing acrylic acids through a reaction with a suitable catalyst. Acrylics are known for excellent environmental resistance and fast-setting times compared to other resin systems.
 
   Bismaleimide (BMI)
 
     Material based on thermoset bismaleimide (BMI) resin. Aromatic polyimides are among the most thermally stable organic materials known. BMI thermoset resins have high temperature resistance. Bismaleimide (BMI) resins have processing characteristics similar to epoxy resins and are used as laminating resins, prepregs, adhesives and other composite applications.
 
   Cellulosic / Cellulose
 
     Polymers are based on a cellulosic or cellulose chemical system. Cellulosic thermoplastics are often used to form plastic films for packaging applications.
 
   Cyanoacrylate
 
     Cyanoacrylates are one-part acrylate adhesives that cure instantly on-contact with mated surfaces through a reaction with surface moisture. Cyanoacrylates are often called super-glues. They have high strength and excellent adhesion to a wide variety of substrates, especially plastics. Potential disadvantages include poor shock or impact resistance (brittleness) and poor gap-filling abilities. Cyanoacrylates that are modified with rubber or elastomers have overcome some of these problems.
 
   Epoxy (EP)
 
     Epoxy resins exhibit high strength and low shrinkage during curing. Epoxies are known for their toughness and resistance to chemical and environmental damage. Most epoxies are two-part resins cured at room temperature. Some thermally-cured or thermoset one-part epoxies are also available. Depending on the formulation, epoxy resins are used as casting resins, potting agents, resin binders or laminating resins in fiberglass or composite construction. They are also used as encapsulants, electrical conductors in microelectronic packaging, and adhesives in structural bonding applications.
 
   Ethylene Copolymer (EEA, EVA, EBAC)
 
     Ethylene copolymers include (poly)ethylene acrylate acid (EAA), (poly)ethylene methyl acrylate (EMAC), (poly)ethylene ethyl acrylate (EEA), (poly)ethylene vinyl acetate (EVA), (poly)ethylene butyl acrylate (EBAC), (poly)ethylene vinyl acetate (EVA or EVAC), (poly)ethylene vinyl alcohol (EVAL or EVOH), and (poly)ethylene propylene terpolymer (EPM).
 
   Fluoropolymer (PTFE / PVDF)
 
     Polymers are based on fluoropolymer chemical systems such as polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF). Fluoropolymers are used in applications requiring superior chemical resistance. PTFE is used in applications requiring superior chemical resistance or low friction.
 
   Ionomer
 
     Thermoplastics are based on the ionomer polymer system.
 
   Liquid Crystal Polymer (LCP)
 
     Liquid crystal polymers (LCP) are thermoplastics with high strength and temperature resistance. Liquid crystal polymers are used in electrical, electronic, and medical applications where the high cost of the material is not an issue.
 
   PEEK / Ketone
 
     Ketones encompass polyaryletherketone or polyetheretherketone (PEEK). PEEK is an engineered thermoplastic that can resist high temperatures. It has excellent chemical resistance, fatigue resistance, and thermal stability. PEEK is inert to all common solvents and resists a wide range of organic and inorganic liquids. PEEK has a maximum continuous working temperature of 480°F, and retains its mechanical properties up to 570°F in steam or high-pressure applications.
 
   Phenolics / Formaldehyde Resins (Melamine, Furan, etc.)
 
     Phenolic and formaldehyde resins are thermosetting molding compounds and adhesives that offer strong bonds and good resistance to high temperatures. Phenolic or phenol formaldehyde, urea formaldehyde, furan, and melamine resins fit into this category. Phenolic resin adhesives made from chemicals of the phenol group and formaldehyde are generally are the most durable. Phenolic resins are available in liquid, powder, and film form. Special phenolic resins are available that harden at moderate temperatures when mixed with suitable accelerators. Phenol-formaldehyde, resorcinol-formaldehyde, resol, and novalac resins are types of phenolic resins. Urea resin adhesives are made from urea, formaldehyde, and catalysts or hardeners. Urea formaldehyde resins can harden rapidly at moderate temperatures, but generally do not have the properties of phenolic resins. Melamine resins are made through a reaction of dicyandiamide with formaldehyde. Most of the resins in this group have excellent dielectric properties. Furan formaldehyde (FF) resins are made by the polymerization or poly-condensation of furfural, furfural alcohol, or other compounds containing a furan ring, or by the reaction of these furan compounds with other compounds (not over 50%).

Fire-retardant furans are used in hand lay-up, spray-up, and filament winding operations. Furans are commonly used in foundry binders, grinding wheels, refractories, and other high temperature applications. Furan resins and chemicals are also used in fiberglass composites, hybrid resins combined with epoxy or phenolics, and in corrosion-resistant cements.
 
   Polyamide
 
     Polyamide is a commonly used system for molding high-strength engineered components. Polyamides are also used to produce strong hot-melt adhesives. Polyamides provide higher strength than polyethylene or other commodity-type polymers.  Nylon is a well-known example of a polyamide engineering resin that is also used to mold plastic parts.
 
   Polyamide-imide (PAI)
 
     Polyamide-imides are amorphous thermoplastic materials with excellent mechanical properties, especially at elevated temperatures. Trimellitic anhydrides react with aromatic diamines to produce polyamide-imides. Polyamide-imides are applied in demanding engineering applications. Solvay Advanced Polymer's Torlon® is a well-known example of a polyamide-imide engineering resin that is also used to mold, extrude or machine plastic parts, or shape stock.
 
   Polybutadiene
 
     Polybutadiene is a commonly used polymer system with dielectric potting compounds and coatings. It can be combined with other rubber polymers to form flexible sealants. Polybutadiene remains flexible even at low temperatures.
 
   Polycarbonate (PC)
 
     Polycarbonate is an amorphous material with excellent impact strength, clarity, and optical properties. Polycarbonate has excellent mechanical properties, and can be molded to tight tolerances. Polycarbonates can be attacked by solvents and petrochemicals. Brand names include Caliber® (Dow) and Lexan® (GE) as well as Makrofol® and Makrolon® (Bayer).
 
   Polyethylene (PE, HDPE, UHMW PE)
 
     Polymers or resins are based on the polyethylene chemical system. Low density polyethylene polymers are used to form a variety of common or commodity-plastic components. High density (HDPE) and ultra-high molecular weight polyethylene (UHMW PE) have good friction and mechanical properties. They are used in medical devices, wear parts, and engineered components.

Mastics fill in gaps or irregularities in a surface before tile or other materials are applied. They are also used to bond tiles to sub-flooring. Repair compounds or gap fillers are used to fill in gaps or repair cavities or holes in a part, casting or structure.  Typically, these compounds may also be used as adhesives or sealants or have sealing or bonding characteristics.
 
   Molding Compound / Molding Grade
 
     Plastics or elastomers suited for the fabrication of parts via injection molding, compression molding, blow molding or film extrusion, reaction injection molding (RIM), resin transfer molding (RTM) or molded stock shapes.


 
   Sealant / Sealing Material
 
     Sealants are liquid compounds used to fill gaps between seams, threads or on surfaces, to contain fluids, prevent leaks, and prevent infiltration of unwanted material. Higher viscosity sealants are used when larger gaps need to be filled.
 
   Thread Locker / Retainer
 
     Threadlocking or threadlocker adhesives bind threads that are subject to transverse and axial loads against vibrational loosening. They reduce production costs and improve reliability by eliminating lock washers and other expensive locking devices. They preserve on-torque and distribute the load over the entire engagement length of the fastener, effectively eliminating premature material fatigue and fastener failure.
