Glass fiber is a kind of inorganic non-metallic material with excellent performance. It has a wide variety. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament ranges from a few microns to 20 microns. Each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments. Glass fiber is usually used as reinforcement in composites, electrical insulation materials and thermal insulation materials, circuit substrates and other fields of the national economy. Glass fiber has higher temperature resistance than organic fiber, non combustible, corrosion resistance, good heat insulation and sound insulation, high tensile strength and good electrical insulation. But it is brittle and has poor wear resistance. Used to make reinforced plastics (see the color picture) or reinforced rubber, as a reinforcing material, glass fiber has the following characteristics, which make the use of glass fiber far more extensive than other kinds of fibers. According to the shape and length, glass fiber can be divided into continuous fiber, fixed length fiber and glass wool. According to the glass composition, it can be divided into alkali free, chemical resistant, high alkali, medium alkali, high strength, high elastic modulus and alkali resistant glass fiber.
