Abstract

A pressurized steam molded multilayer lining for heat and sound insulation comprising a first layer forming a reinforcement layer made of a blended web of polyamide matrix material in the form of powder or fibers or flakes and reinforcement fibers, and at least a second layer chosen from an open cell foam layer, or a heat reflecting layer, or a second reinforcement layer made of a blended web of polyamide matrix material in the form of powder or fibers or flakes and reinforcement fibers, and whereby due to the pressurized steam molding, all layers are laminated together and all available blended webs are consolidated to form porous reinforcement layers.
