What is GRP/FRP?

Glass fiber reinforced plastic (GRP/FRP), also known as fiberglass reinforced plastic, is a composite material made of polymer epoxy resin as the matrix and glass fiber or carbon fiber as the reinforcement through a composite process.

Glass is hard and brittle, with good transparency, high temperature resistance, corrosion resistance and other properties; steel is very hard and not brittle, and also has high temperature resistance. So people began to think that if they could create a material that not only had the hardness, high temperature resistance, and corrosion resistance of glass, but also had the characteristics of being as hard and unbreakable as steel, then this material would be of great use.
