Thermoplastically deformable composite material

Abstract

Thermoplastically deformable composite materials have a core layer with a glass fiber woven ply connected on both sides thereof to a fiber nonwoven ply of polypropylene fibers and glass fibers. The core layer is connected with at least one cover layer which comprises polypropylene fibers and polyethylene terephthalate fibers. The composite materials are produced by needling the individual layers and heating to melt the polypropylene fibers. The composite materials are useful for preparing automotive parts.
