What is Fiberglass？
Glass fiber is an inorganic, non-metallic material and a man-made inorganic fiber. It utilizes industrial technologies from mechanics, metallurgy, thermal engineering, chemicals, textiles, and automation to melt natural minerals such as quartz sand, limestone, dolomite, kaolin, and pyrophyllite, along with other chemical raw materials such as soda ash and boric acid, into glass. From this molten state, it is then drawn, blown, or spun into extremely fine fibers using external forces. Glass fiber, primarily composed of silica, alumina, calcium oxide, and magnesium oxide, offers excellent properties such as lightweight, high strength, high and low temperature resistance, corrosion resistance, thermal insulation, flame retardancy, sound absorption, and electrical insulation, as well as a degree of functional designability, making it an excellent functional and structural material.
Glass fiber can be manufactured into various forms, including yarn, cloth, and tape. Glass fiber cloth can be used as a reinforcement in mica insulation materials and as a base fabric for other industrial materials. The downstream applications of glass fiber cloth are primarily concentrated in transportation, construction and infrastructure, electronics, and environmental protection. Fiberglass cloth is commonly used in construction projects, graded highways, asphalt concrete pavements, bridges, and other fields. Furthermore, with the continuous emergence of new fiberglass products, it is increasingly being used in various new building materials. Furthermore, electronic fiberglass cloth, when fused with resin to create copper-clad laminates, serves as a specialized base material for printed circuit boards (PCBs), which are then widely used in electronic products such as smartphones, computers, and tablets.
