What is glass fiber reinforced plastics (FRP)

FRP: in fact, it is commonly known as FRP.

The scientific name of FRP is glass fiber reinforced plastics. It is a kind of composite material with 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 that one kind of material can not meet the use requirements, and it needs to be composed of two or more kinds of materials to form another kind of material that can meet people's requirements, namely composite material. For example, although a single kind of glass fiber has high strength, it is loose among the fibers. It can only bear tensile force, but can not bear bending, shearing and compressive stress. It is not easy to make a fixed geometry and is loose soft. 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 makes glass fiber reinforced plastic matrix composites. Because its strength is equivalent to steel and contains glass components, it also has the same color, shape, corrosion resistance, electrical insulation, heat insulation and other properties as glass. Like glass, this easy to understand name "FRP" has been formed in history. This term was proposed by Lai Jifa, former Minister of the Ministry of building materials industry of the people's Republic of China in, and expanded from building materials system to the whole country, Now it is still widely used. It can be seen that the meaning of glass fiber reinforced plastics refers to the reinforced plastics with glass fiber as reinforcement material and synthetic resin as binder. With the development of China's FRP industry, as a plastic based reinforcing material, it has 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 composites, which can not be generalized by the common name of FRP. Considering the origin and development of history, FRP composite materials are usually used. Such a name is more comprehensive.
