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 cloth is mostly used for hand lay-up process, and glass fiber reinforced material checker cloth is mainly used for hull, storage tank, cooling tower, ship, vehicle, tank and building structural materials. Glass fiber cloth is mainly used in industry for heat insulation, fire prevention and flame retardance. This material absorbs a lot of heat when it is burned by flame and can prevent flame from passing through and isolate air.
