Claim:
1. A method for manufacturing an equipment part of an automotive vehicle comprising the following steps: providing a base layer including ceramic fibers and heat fusible polymer fibers; heating and compressing the base layer on at least one supporting wall for melting the hot melt polymer fibers and having the molten polymer adhere to the ceramic fibers in order to obtain a preformed layer; confining the preformed layer in a pressurized mold in order to make up a formed layer, wherein the method includes arranging a first sheet of porous material on a first face of the base layer and a second sheet of porous material on a second face of the base layer before the heating step, at least the first sheet of porous material being formed with paper, each sheet of porous material having a thickness of less than that of the formed layer, the sheets of porous material confining between them the molten polymeric material stemming from the heat fusible polymer fibers during the heating step, the sheets of porous material being bound to the formed layer after the step for making up the formed layer, in order to form a first composite body, wherein the method includes: making a second composite body, attaching the first composite body and the second composite body onto opposite faces of an intermediate spacer having cellulose fibers, said attaching step including adhesively bonding the first sheet of porous material of the first composite body against said intermediate spacer.
