Fiberglass reinforced plastic (FRP), also known as GFRP, is fiber reinforced plastic, which generally refers to the matrix of unsaturated polyester, epoxy resin and phenolic resin reinforced with glass fiber. Reinforced plastic with glass fiber or its products as reinforcing material is called glass fiber reinforced plastic, or glass fiber reinforced plastic, which is different from tempered glass. Because of the different types of resins used, it is known as polyester fiberglass, epoxy fiberglass and phenolic fiberglass. Light and hard, non-conductive, stable performance. High mechanical strength, less recycling, corrosion resistance. It can replace steel to make machine parts and car, ship shell and so on.
Fiberglass reinforced plastics, commonly known as FRP (Fiber Reinforced Plastics), are fiber reinforced composite plastics. According to the different fibers selected, it is divided into glass fiber reinforced composite plastics (GFRP), carbon fiber reinforced composite plastics (CFRP), boron fiber reinforced composite plastics, etc. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as the reinforcing material and synthetic resin as the matrix material. Fiber-reinforced composite materials are composed of reinforcing fibers and a matrix. The diameter of the fiber (or whisker) is very small, generally below 10 μm, with fewer defects and smaller, and the cracking strain is less than 30/1000. It is a brittle material and is easily damaged, cracked and corroded. Compared with fibers, the strength and modulus of the matrix are much lower, but it can withstand large strains, and often has viscoelasticity and elastoplasticity, which is a resistant material.
