Glass fiber reinforced plastics.It is based on glass fiber and its products (glass cloth, tape, felt, yarn, etc.) as reinforcement materials, with synthetic resin as a matrix material of a composite material.The concept of composite material refers to a material can not meet the use requirements, need to be composed of two or more kinds of materials together, to meet the requirements of another material, that is, composite material.For example, a single type of glass fiber, although very strong, is loose between the fibers, can only withstand tension, can not withstand bending, shear and compression stress, is not easy to make a fixed geometry, is a soft body.When they are glued together with synthetic resins, they can be made into rigid products of fixed shapes that can withstand tensile stresses as well as bending, compression and shearing stresses.This constitutes a glass fiber reinforced plastic matrix composite.Due to its strength of steel, and glass components, also has a glass color, shape, such as corrosion resistance, electrical insulation, heat insulation performance, such as glass, formed in the history of this easy to understand the name of the "glass", by the former national building materials industry minister this noun is Lai Ji comrades in 1958, the building materials system expansion to the nation, is now also widely used.It can be seen that the meaning of glass fiber reinforced plastics refers to glass fiber as a reinforcing material, synthetic resin as a binder, called glass fiber reinforced plastics abroad.With the development of China's glass fiber reinforced plastic, as reinforced material of plastic base, is made of glass fiber expanded to carbon fiber, boron fiber, aramid fiber, silicon carbide fiber and alumina fiber, there is no doubt that these new type of fiber reinforced plastics, are some high performance fiber reinforced composites, the commonly known as cannot be summarized with glass fiber reinforced plastic.Considering the history of the origin and development, usually using glass reinforced plastic composite materials, such a name is more comprehensive.
