Fiber reinforced plastic (FRP) is a composite material made of a polymer matrix reinforced with fibers. The fibers, which are usually glass, carbon, basalt or aramid, increase the strength and stiffness of the polymer. FRP has high strength-to-weight ratio, corrosion resistance, and design flexibility. It is used in applications like pipes, walkways, and construction where these properties are beneficial. However, FRP has low strength perpendicular to the fibers and complex manufacturing requirements.
