Fiberglass fabric is a fabric made of glass fibers (see inorganic fibers). With insulation, heat insulation, corrosion resistance, non-combustion, high temperature resistance, high strength and other properties, mainly used as insulation materials, glass fiber reinforced plastic materials, chemical filter cloth, high pressure steam insulation materials, fire products, high elastic transmission belt, building materials and wall covering. The glass is brittle, and the thicker glass fiber is easy to break when weaving, so the fiber diameter generally used for weaving glass cloth is 3.8 to 15.5 microns. Glass fibers can be made into filaments and spun yarns.
