The concept of FRP composite material means that one material cannot meet the requirements for use, and the title is required to be composed of two or more materials to form another material that can meet people's requirements, that is, a composite material.
For example, a single type of glass fiber, although high in strength, is loose between fibers, can only withstand tensile forces, cannot withstand bending, shearing and compressive stress, and is not easily made into a fixed geometric shape. If they are bonded together with synthetic resin, they can be made into a variety of rigid products with a fixed shape, which can withstand both tensile stress, bending, compression and shear stress. This constitutes a glass fiber reinforced plastic-based composite material.
Because its strength is equivalent to steel, and it also contains glass components, it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of glass. Like glass, this easy-to-understand name "glass steel" has been formed in history. The term was proposed by Comrade Lai Jifa, former Minister of the National Building Materials Industry, in 1958, and was expanded from the building materials system to the whole country. The meaning of glass fiber reinforced plastic refers to glass fiber reinforced plastics and synthetic resins as reinforcing plastics. It is called glass fiber reinforced plastics abroad. With the development of China's FRP industry, as a plastic-based reinforcing material, it has been expanded from glass fiber to carbon fiber, boron fiber, aramid fiber, alumina fiber, and silicon carbide fiber. Undoubtedly, these new fiber reinforced plastic , Are some high-performance fiber-reinforced composite materials, and then the common name of glass fiber reinforced plastic can not be generalized.
