The Principle Of FRP Materials

Jul 29, 2020

The concept of  FRP material refers to a material that cannot meet the requirements of use, and it needs to be composed of two or more materials to form another material that can meet people's requirements, namely composite materials. The following editor introduces the principle of FRP materials.


FRP material


   For example, although a single type of glass fiber has high strength, it is loose between the fibers and can only withstand tensile forces. It cannot withstand bending, shearing and compressive stress, and it is not easy to form 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 as well as bending, compression and shear stress. This constitutes a glass fiber reinforced plastic matrix composite material. Because its strength is equivalent to steel, but also contains glass components, it also has the same color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of glass. The meaning of FRP material refers to reinforced plastic with glass fiber as reinforcing material and synthetic resin as binder. It is called glass fiber reinforced plastic in foreign countries. With the development of China's FRP business, as a plastic-based reinforcement material, glass fiber has expanded to carbon fiber, boron fiber, aramid fiber, alumina fiber and silicon carbide fiber. Undoubtedly, reinforced plastics made of these new fibers , Is some high-performance fiber-reinforced composite materials, considering the origin and development of history, glass fiber reinforced plastic composite materials are usually used.
