Fiberglass is a high-performance material with a wide range of applications. Fiberglass was born in the 1930s. It is an inorganic non-metallic material produced from main mineral raw materials such as pyrophyllite, quartz sand, limestone, dolomite, colemanite, and magnesia stone, as well as chemical raw materials such as boric acid and soda ash. It has excellent properties such as light weight, high strength, high and low temperature resistance, corrosion resistance, heat insulation, flame retardancy, sound absorption, electrical insulation, and a certain degree of functional designability. It is an excellent functional material and structural material. In recent years, fiberglass thermoplastic reinforced materials have developed rapidly. New products such as fiberglass reinforced building materials, short fiber and long fiber direct reinforced materials have become new highlights in the development of the fiberglass industry. The application of fiberglass has expanded from traditional industrial fields such as construction and building materials, electronic appliances, rail transportation, petrochemicals, and automobile manufacturing to emerging fields such as aerospace, wind power generation, filtration and dust removal, environmental engineering, and marine engineering.
