glass fiber reinforced plastic material: the scientific name of glass fiber reinforced plastic material is glass fiber reinforced plastic. It is a composite material with glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as the reinforcing material and synthetic resin as the matrix material. The concept of glass fiber reinforced plastic composite material refers to a material that cannot meet the requirements of use, and needs to be composed of two or more materials to form another material that can meet people's requirements, namely composite materials. For example, although a single type of glass fiber has high strength, it is loose between the fibers and can only withstand tension, not bending, shearing and compressive stress, and it is not easy to be formed into a fixed geometric shape. It is loose soft. If they are glued together with synthetic resin, they can be made into a variety of rigid products with a fixed shape, which can withstand tensile stress, but also withstand bending, compression and shear stress. This constitutes a glass fiber reinforced plastic matrix composite material. Because its strength is equivalent to steel, it also contains glass components, and it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of glass. Like glass, it has historically formed this easy-to-understand name glass steel" This term was put forward by Comrade Lai Jifa, the former Minister of the Ministry of Building Materials Industry in 1958, and expanded from the building materials system to the whole country, and it is still widely used.
FRP composite material
It can be seen that the meaning of FRP materials refers to reinforced plastics with glass fiber as a reinforcing material and synthetic resin as a binder. It is called glass fiber reinforced plastic in foreign countries. With the development of China's fiberglass material industry, as a plastic-based reinforcement material, glass fiber has expanded to carbon fiber, boron fiber, aramid fiber, alumina fiber and silicon carbide fiber. Undoubtedly, the reinforcement made of these new fibers Plastics are some high-performance fiber-reinforced composite materials, and the common name of glass fiber reinforced plastic materials cannot be generalized. Taking into account the origin and development of history, FRP composite materials are usually used, so a name is more comprehensive
