Fiberglass Sandwich Fabric PP Core Mat 450/250/450

Fiberglass sandwich fabric complex mat
 
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.
This fabric is compatible with UP Resin, Vinyl ester resin, epoxy resin system etc. It is widely used in closed mould applications for vehicle bodies and panels, marine (boat hulls and decks), windmill nacelles, leisure vehicle and structural shapes.
