Light, acoustically insulating cladding for a bodywork section or for a component of a motor vehicle and its method for producing

摘要

The light, sound proofing panel (20) has a porous layer (43) made of a stable fiber web composed of thermoplastic fiber, which is arranged between acoustic absorbers (23) made of foamed plastic (34). The material of a staple fiber web (44) and the foam material (35) of another acoustic absorber (33) form one or more noise damping layers (27). The staple fiber web is made of Polypropylene fibers or polyester fibers. An independent claim is also included for a method for manufacturing light, sound proofing panel.
