Due to the different types of resins used, there are polyester FRP, epoxy FRP and phenolic FRP. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling and corrosion resistance. It can replace steel to make machine parts and automobile and ship shells.
The scientific name of glass fiber reinforced plastic, commonly known as FRP (fiber reinforced plastic), is a fiber reinforced composite plastic. According to the different fibers used, it can be divided into glass fiber reinforced composite plastics (GFRP), carbon fiber reinforced composite plastics (CFRP) and boron fiber reinforced composite plastics. It is a composite material composed of glass fiber and its products (glass cloth, adhesive tape, felt, yarn, etc.). ) as reinforcing material, synthetic resin as matrix material. Fiber reinforced composites are composed of reinforcing fibers and matrix. The diameter of fiber (or whisker) is very small, generally below 10μm, with few defects and small fracture strain of about 30 ‰. It is a brittle material, which is easy to be damaged, broken and corroded. Compared with fiber, the strength and modulus of matrix are much lower, but it can bear large strain and often has viscoelasticity and elastoplasticity, so it is a tough material.
