Fiberglass

Glass fiber (abbreviated as GF) is a type of fiber made from glass, formed through processes such as molten fiber drawing or blowing. It features high strength, high temperature resistance, corrosion resistance, and excellent electrical insulation. It is the most commonly used reinforcement material in composite materials, especially in FRP/GRP materials such as unsaturated polyester resin and epoxy resin.
