Graphite fiber reinforced plastic

Based on contents of an RP other terms are used to identify an RP. Examples include glass fiber reinforced plastic (GFRP), aramid fiber reinforced plastic (AFRP), carbon fiber reinforced plastic (CFRP), graphite fiber reinforced plastic (GFRP), boron fiber reinforced plastic (BFRP), etc. 

Set-up men employ carbon or graphite fiber-reinforced plastic fabrics, prepregs, supplied as pliable cloth impregnated with a liquefied binder, such as... 

Limited at first to the inspection of metallic components, it was later demonstrated that high-frequency magnetic fields causing eddy current production could be applied to the testing of composites containing conductive fibers, or a certain amount of graphite [108.109], Eddy current testing has been successfully applied in the detection and characterization of defects in carbon fiber reinforced plastics (CFRP) panels, helicopter rotor blades, truck tires, and more [110-112]. 

In the manufacture of fine chemicals, SS-304/SS-316/SS-316L is a commonly used material of constructions. For other duties, special materials such as SS-304 ELC, glass lined, fiber reinforced plastic (FRP), graphite, etc. may be required to counter... 

Carbon-Fiber-Reinforced Plastics n (CRP) Plastics, either thermosetting or thermoplastic - most commonly epoxies or high-performance resins - that contain carbon or graphite fibers (Chung DD (1994) Carbon fiber compositers. Elsevier Science and Technology Books, New York). 

High performance composites may be laminates wherein veils of carbon fiber ate treated with an epoxy resin, stacked up to the desired final product thickness, and then laminated together under heat and pressure (see Composite materials Carbon and graphite fibers). Simply mixing together carbon or glass fibers and polymeric resins to form a reinforced plastic leads to a composite material, but this is not a laminate if not constmcted from discrete phes. 

Fiber-reinforced composite materials such as boron-epoxy and graphite-epoxy are usually treated as linear elastic materials because the essentially linear elastic fibers provide the majority of the strength and stiffness. Refinement of that approximation requires consideration of some form of plasticity, viscoelasticity, or both (viscoplasticity). Very little work has been done to implement those models or idealizations of composite material behavior in structural applications. 

Because people everywhere tend to take their fun seriously, they spend freely on sports and recreational activities. The broad range of properties available from plastics has made them part of all types of sports and recreational equipment for land, water, and airborne activities. Roller-skate wheels are now abrasion- and wear-resistant polyurethane, tennis rackets are molded from specially reinforced plastics (using glass, aramid, graphite, or other fibers), skis are laminated with plastics, and so on. 

By this time the industry required a more inclusive term to describe RPs, so composite was added. Thus the name in the plastics industry became Reinforced Plastic Composites. More recently they became known only as Composites. However composites identify many other combinations of basic materials (Table 6-18). The fiber reinforcements included higher modulus glasses, carbon, graphite, boron, aramid (strongest fiber in the world, five times as strong as steel on an equal-weight basis), whiskers, and others (Table 6-20 and Figs. 6-13 and 6-14). In... 

Expansion and contraction can be controlled in plastic by its orientation, cross-linking, adding fillers or reinforcements, and so on. With certain additives the CLTE value could be zero or near zero. For example, plastic with a graphite filler contracts rather than expands during a temperature rise. RPs with only glass fiber reinforcement can be used to match those of metal and other materials. In fact, TSs can be specifically compounded to have little or no change.
