Fibre-reinforced plastic (FRP), also known as fiber-reinforced polymer (FRP), is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass (in fiberglass), carbon (in carbon-fiber-reinforced polymer), aramid, or basalt. Rarely, other fibers such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries.
