Carbon fiber reinforced polymer From Wikipedia, the free encyclopedia Jump to navigation Jump to search "Carbon fiber" redirects here. For fibers of carbon, see carbon fibers . Tail of a radio-controlled helicopter , made of CFRP Carbon fiber reinforced polymer , carbon fiber reinforced plastic or carbon fiber reinforced thermoplastic ( CFRP , CRP , CFRTP or often simply carbon fiber , carbon composite or even carbon ), is an extremely strong and light fiber-reinforced plastic which contains carbon fibers . The alternative spelling 'fibre' is common in British Commonwealth countries. CFRPs can be expensive to produce but are commonly used wherever high strength-to-weight ratio and rigidity are required, such as aerospace, automotive, civil engineering, sports goods and an increasing number of other consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy , but other thermoset or thermoplastic polymers, such as polyester , vinyl ester or nylon , are sometimes used. The composite may contain aramid (e.g. Kevlar , Twaron ), aluminium , ultra-high-molecular-weight polyethylene (UHMWPE) or glass fibers in addition to carbon fibers. The properties of the final CFRP product can also be affected by the type of additives introduced to the binding matrix (the resin). The most frequent additive is silica, but other additives such as rubber and carbon nanotubes can be used. The material is also referred to as graphite-reinforced polymer or graphite fiber-reinforced polymer ( GFRP is less common, as it clashes with glass-(fiber)-reinforced polymer).

In this case the composite consists of two parts: a matrix and a reinforcement. In CFRP the reinforcement is carbon fiber, which provides the strength. The matrix is usually a polymer resin, such as epoxy, to bind the reinforcements together.  Because CFRP consists of two distinct elements, the material properties depend on these two elements. The reinforcement will give the CFRP its strength and rigidity; measured by stress and elastic modulus respectively. Unlike isotropic materials like steel and aluminum, CFRP has directional strength properties. The properties of CFRP depend on the layouts of the carbon fiber and the proportion of the carbon fibers relative to the polymer.  The two different equations governing the net elastic modulus of composite materials using the properties of the carbon fibers and the polymer matrix can also be applied to carbon fiber reinforced plastics.
