The concept of composite material refers to that one kind of material can not meet the use requirements, and it needs to be composed of two or more materials together to form another kind of material that can meet people's requirements, namely composite material. For example, a single type of glass fiber, although of high strength, is loose between fibers, which can only bear tensile force, can not bear bending, shearing and compressive stress, and is not easy to make a fixed geometry, which is loose software. If they are bonded together with synthetic resin, they can be made into various hard products with fixed shape, which can bear not only tensile stress, but also bending, compression and shear stress. This constitutes a glass fiber reinforced plastic matrix composite. Due to its strength equivalent to steel and containing glass components, it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of glass. Like glass, this common name "glass fiber reinforced plastics" has been formed in history. The term was written in 1958 by Comrade Lai Jifa, former Minister of building materials industry of China Proposed in, the building materials system is expanded to the whole country, and is also widely used. It can be seen that the meaning of fiberglass refers to the reinforced plastics with fiberglass as reinforcement material and synthetic resin as binder, which is called fiberglass reinforced plastics abroad. With the development of FRP industry in our country, as the reinforced material of plastic base, it has been expanded from glass fiber to carbon fiber, boron fiber, aramid fiber, alumina fiber and silicon carbide fiber. Undoubtedly, the reinforced plastics made of these new fibers are some high-performance fiber-reinforced composite materials, which can not be generalized by the common name of FRP. In view of the origin and development of history, FRP composite materials are usually used, so a name is more comprehensive.
