Fiberglass stitched mat is made from chopped fiberglass strands or woven roving which is cut into a certain length and randomly dispersed ,laid on a roving matrix then stitched together with organic fibers. Even thickness, high wet tensile strength retention Directional properties and strengths same to woven roving Enough hollows on surface to make it good permeability Flexibility to design variety weaving structures Stable structure required to achieve maximum tensile strength properties Fiberglass stitched mat is used in unsaturated polyester resin strenthen, primarily in pultrusion, RTM, filament winding and hand lay-up processed. Such as pultruded parts, pipes, storage tanks, wind generator blades and other FRP products.
