2627 Use of Composite Materials

A fiber-reinforced polymer composite or a FRP is a matrix of polymeric material reinforced by fibers or other reinforcement that has a discernible aspect ratio of length to thickness. Reinforcements are fibers made from glass, carbon, or aramid, and the polymer resin can be either thermoset or thermoplastic. Thermosets are typically used for construction applications and can be polyester, vinyl ester, phenolic, or epoxy. FRP composites have been used in a variety of engineering products.
