Glass fiber is a kind of inorganic nonmetallic material with excellent performance, with a wide variety of advantages, such as good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Glass fiber is usually used as reinforcing material in composite materials, electrical insulation material, thermal insulation material, circuit substrate and other fields of national economy.

Glass fiber has higher temperature resistance, incombustibility, corrosion resistance, heat insulation, sound insulation, high tensile strength and good electrical insulation than organic fiber. However, it is brittle and has poor wear resistance. The glass fiber used to manufacture reinforced plastics or reinforced rubber, as a reinforcing material, has the following characteristics. These characteristics make the use of glass fiber far more extensive than other types of fibers, and the development speed is also far ahead.
