What is FRP

Glass fiber reinforced plastic (FRP) is also called GFRP, which is fiber reinforced plastic. It generally refers to the reinforced plastic with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix and glass fiber or its products as reinforcement materials. It is called glass fiber reinforced plastic or glass fiber reinforced plastic, which is different from tempered glass.

Due to the different resin varieties used, there are polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic glass fiber reinforced plastics. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling, corrosion resistance. It can replace steel to make machine parts, automobile and ship shells.

The scientific name of FRP is fiber reinforced plastics, commonly known as FRP (Fiber Reinforced Plastics), which is fiber reinforced composite plastics. It can be divided into glass fiber reinforced plastic (GFRP), carbon fiber reinforced plastic (CFRP) and boron fiber reinforced plastic according to the different fibers used. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcement materials and synthetic resin as matrix materials. Fiber reinforced composite is composed of reinforced fiber and matrix. The diameter of fiber (or whisker) is very small, usually 10 μ Below m, there are fewer and smaller defects, and the fracture strain is less than 30 ‰. It is a brittle material, which is easy to be damaged, fractured and corroded. The strength and modulus of the matrix are much lower than those of the fiber, but it can withstand large strains, often with viscoelasticity and elastoplasticity, and is a ductile material.
