Glass fiber is a material made from very fine strands of glass. It is lightweight, strong, and resistant to corrosion, making it useful in a variety of applications. Commonly used in construction, automotive, and aerospace industries, glass fiber can be molded into different shapes and combined with resins to create composite materials. The production of glass fiber involves melting silica sand and other raw materials at high temperatures, then drawing the molten glass into thin fibers. These fibers can be woven into fabrics or used as reinforcement in products like boats, wind turbine blades, and insulation.
