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
