FAQ
1. Q: What's FRP?
Fiber Reinforced Polymer (FRP) is a composite material made of a polymer matrix reinforced with fibers. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper or wood or asbestos have been used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and formaldehyde resins are still in use. FRP are commonly used in the aerospace, automotive, marine, construction industries and ballistic armor.
