Fiberglass Reinforced Plastic (FRP) is a composite plastic with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin as the matrix material. FRP materials have the characteristics of light weight, high specific strength, corrosion resistance, good electrical insulation, slow heat transfer, good thermal insulation, good resistance to transient ultra-high temperatures, as well as easy colouring and transmission of electromagnetic waves. As a kind of composite material, FRP is widely used in aerospace, railway and railway, decorative construction, home furniture, building materials, sanitary ware and sanitation engineering and other related industries due to its unique performance advantages.
