Glass fiber(English name is): It is a kind of excellent inorganic non-metallic materials, having the advantages of good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage of poor brittleness, poor abrasion resistance. It is founding by high tempersture with the materials of glass ball and waste glass, and wire drawing, winding and weaving process for production, the filament diameter ranges from several microns to twenty micron, the equivalent of a hair 1\20-1\5, and each bundle of fibers by hundreds or even thousands of root filaments. Usually it is treated as a reinforcing material of complex materials, electrical insulating materials and insulation materials, circuit board, etc. and widely used in various fields of the national economy. The tensile strength of glass fiber is high, and the elongation is small (3%).
From the performance, it could be divided in wind power yarn, chopped yarn, glass pipes, thermoplastic filament winding, yarn, plastic heat wind blade, fiber, transparent tile, computer motherboard, fishing rod, transparent sheet yarn, forming the way points directly from the yarn and cake, SMC yacht accessories, rocket parts and so on. It is also used widely, like car roof, electronic yarn cloth, mobile phone motherboard
