What is the material of glass fiber

Glass fiber is an inorganic non-metallic material. The utility model has the advantages of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, while the disadvantages are brittle and poor wear resistance. Inorganic non-metallic materials are made from pyrophyllite, quartz sand, limestone, dolomite, borocalcite and boromagnesite through a series of processes. When glass fiber is used as reinforcing material of reinforced plastics, the biggest feature is high tensile strength. The tensile strength is 6.3 ~ 6.9 g / D in the standard state.

The main components of glass fiber are silica, alumina, calcium oxide, boron oxide, etc. According to the alkali content in glass, it can be divided into non alkali glass fiber, medium alkali glass fiber and high alkali glass fiber.

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, glass fiber can be divided into alkali free, chemical resistant, high alkali, medium alkali, high strength, alkali resistant glass fiber, etc. (BoLiQianWeiShiShenMeCaiLiao)
