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.
Claims22
A multilayer formed part having acoustic damping properties, comprising:
- a binder containing carrier fibrous web having two opposed sides the web formed from at least one of natural and synthetic fibers of low compression;
- at least one of a cover layer and a decorative layer disposed on both sides;
- and
- a plurality of prismatic regions of a predetermined cross section interlaced within and distributed across the fibrous web, each of the plurality of prismatic regions being surrounded by carrier fibrous web, the prismatic regions being connected in a shear resistant manner with at least one of the cover layer and the decorative layer;
- wherein the plurality of prismatic regions render the multilayer formed part with a predetermined rigidity.
