The basic components of FRP profiles are resin and glass fiber (including cloth, felt, etc.). It uses fiber (including glass fiber, carbon fiber, organic fiber and other metal and non-metal fibers) as reinforcing materials. It is composed of resin as the adhesive agent and other auxiliary materials (main auxiliary materials: release agent, curing agent, catalyst, sealing agent, UV light stabilizer, mold cleaning water, gel coat, etc.). It has a series of properties such as high temperature resistance, corrosion resistance, high strength, small specific gravity, low moisture absorption, small extension and good insulation.
