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. Roving roving is composed of parallel raw silk or parallel filament bundling. Roving glass can be divided according to the composition. Alkali free glass twistless roving and middle alkali glass twistless roving. The glass fiber diameter from 12～23μm is used in the production of glass roving. Roving the number from 150 to 9600 (Tex). The twistless roving can be directly used in some composite materials, with the charact of high glass fiber content.
It is a kind of excellent inorganic non-metallic materials, having the advantages of good insulation, good corrosion resistance, which is equivalent to a piece of hair. It is founding by high temperature with the raw materials of glass ball and waste glass. It has the advantages of high mechanical strength, electrical insulating and thermal insulation and heat resistance. Each bundle of fibers is made of hundreds or even thousands of root filaments. The diameter range from several microns to twenty micron.
