ABSTRACT:
According to one aspect of the invention, a multi-layer automotive interior trim panel (10) comprises a decorative covering layer (12) and a supportive substrate layer (16). The substrate layer (16) is comprised of a rigid material formed into a predetermined shape for supporting the covering layer. The trim panel also includes an intermediate layer (18) disposed between the covering layer and the supportive substrate layer comprised of cushioning material. The intermediate layer includes a mat (20) of polymeric fibers, with the mat having a plurality of indentations (24) to provide a cushioning effect. A corresponding method for producing the interior trim panel having the three layers includes several steps. The first step is heating the cushion layer (18) to a predetermined temperature. The second step is melting a portion of the polymeric fibers in the cushion layer. The third step is stamping the cushion layer to form the plurality of indentations (24). The next step is adhering the cushion layer (18) to the covering layer (12) and the support layer (16) to form the trim panel (10).
