Also called Combo Matt.
Stitch matt is made up of glass fibre laid randomly and held together by stitching. It is constructed using a layer of woven roving to which a controlled quantity of chopped strand is deposited and stitched. This binderless structure provides excellent drape ability, high glass content and higher tensile strength than a normal Chopped Strand Matt. This stitched matt can be used for hand lay-up but is more suited for pultrusion and closed mold applications.
A layer of polyester veil can be added for better surface finish and weather resistant property.
