This mat is the multi-layered combination mat, generally made by mechanically stitching layers of roving or woven roving or chopped strand, in this case to one or both sides of synthetic fiber core (PP or PET), like a sandwich. The complex mat generally also be made from a combination of woven roving which are mechanically stitched with mats made of chopped strand to form the “bread”. Some complex mat even have no roving or fabric (i.e. complexes stitched from mats and veils without fabric layers). In all cases, the layers are mechanically stitched to the synthetic fiber core. It is mainly applied in the hand lay up, RTM and other close molding processes.
