Glass fiber reinforced plastics. The utility model relates to a composite material which is made of glass fiber and its products (glass cloth, belt, felt, yarn, etc.) as reinforcing material and synthetic resin as matrix material. The concept of composite material is a material can not meet the use requirements, the need to be composed of two or more than two kinds of materials together to form another material that can meet the requirements of people, that is, composite materials. For example, a single kind of glass fiber, although the intensity is very high, but the fiber is loose, can only bear the tensile force, can not withstand bending, shear and compressive stress, but also not easy to make a fixed geometry, is loose. If they are bonded together by a synthetic resin, they can be made into a variety of rigid products with a fixed shape, which can withstand tensile stress and bear bending, compression and shear stresses. This constitutes a glass fiber reinforced plastic matrix composites. Because of the strength of the equivalent steel containing glass components, also has the properties of glass color, shape, corrosion resistance, electrical insulation, insulation such as glass, as the history of the formation of popular name "glass steel", the term was coined by the former national building materials industry minister Comrade Lai Jifa in 1958, the building system expanded to the whole country, it is widely used.
Thus, the meaning of FRP refers to the use of glass fiber reinforced materials, synthetic resin as the binder of reinforced plastics, said the glass fiber reinforced plastics.
With the rapid development of China's glass steel industry, as a reinforcing material of plastic base, has been expanded to glass fiber carbon fiber, boron fiber, aramid fiber, alumina fiber and silicon carbide fiber reinforced plastics, no doubt, these new fibers, some high performance fiber reinforced composite materials, glass and steel this cannot be summarized as.
