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 draws glass into very fine glass fiber, which has good flexibility at this time. The glass fiber can be spun into yarn and then woven into glass fiber cloth by weaving machine. Due to the extremely fine glass fiber and the large positive surface per unit mass, the temperature resistance has decreased. Just like a candle can melt a thin copper wire.
