Abstract

A multilayer formed part having acoustic damping properties is composed of a binder containing carrier fibrous web of natural fibers and/or synthetic fibers of low compression, which is covered at both sides with cover layers and/or decorative layers. The carrier fibrous web across the surface thereof is interlaced with prismatic regions of any suitable cross section, with prismatic regions having increased strength and not being connected with each other, and being connected to the covering layer and/or the decorative layer in a shearing resistant manner.
