An automobile part () for acoustic screening makes it possible to insulate a passage of a through unit (). The automobile part () for acoustic screening is a part () in a single piece with different areas of density and/or rigidity, such as to constitute lips () at the through passage of the mobile unit ().

Automobile part for acoustic screening and its production process

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.

Moulded multilayer lining for heat and sound insulation

Production method for a multilayer lining for thermal and sound insulation with the steps of blending reinforcement fibers and polyamide matrix material, in the form of fibers, flakes or powder, and forming a web of said blend; layering said blended web and at least an additional layer chosen from an open cell foam layer, a heat reflective layer, or another of said blended web inside a mold; treating the stacked multilayer material with pressurized saturated steam, such that the polyamide matrix material in the blended web is melting at a temperature under steam pressure that is lower than the melting temperature of the polyamide matrix according to DSC, thereby binding the reinforcement fibers together thus consolidating the blended web forming a porous reinforcement layer, and all layers of the multilayer are laminated together.
