SP’s Fibre-reinforced polymer (FRP), also Fibre-reinforced plastic, is a composite material made
of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon, or aramid, although
other fibres such as paper or wood or asbestos have been sometimes used. The polymer is usually
an epoxy, vinylester or polyester thermosetting plastic, and phenol formaldehyde resins are still in
use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries.
