Glass fibre is an important reinforcement in crack-resistant protective layers in many industries and is also widely used in external insulation systems. Glass fibre is produced from seven minerals — pyrophyllite, quartz sand, limestone, dolomite, borocalcite and boromagnesite — through high-temperature melting, drawing, winding and weaving.
Glass fibre is an inorganic non-metallic material with excellent performance, composed mainly of silica, alumina, calcium oxide, boron oxide, magnesium oxide and sodium oxide. One of its common uses is as a reinforcing modifier added to plastics: an appropriate amount of glass fibre achieves the stiffness and strength required by the material design, so glass fibre content is one of the common quality control parameters in practice.
