The invention relates to a component part, especially a rear parcel shelf, and to a method for the production thereof, whereby the component part is provided with a honeycomb-like core layer ( ) which is provided with a reinforcing layer ( ) on each side. This layer comprises a nonwoven that contains thermoplastic fibers. The core layer ( ) is made of thermoplastic material and is connected to the thermoplastic fibers of the reinforcing layer ( ) b material fit. The reinforcing layer ( ) is precompressed and air permeable and has an air flow resistance ranging from 500 Nsm <R<3500 Nsm .

Acoustically effective rear parcel shelf

The invention provides a lightweight vehicle flooring assembly, wherein a carrier layer ( ) has a layered structure. This structure comprises a honeycomb-like core layer ( ) which can be made of a suitably impregnated cardboard material and which is connected on both sides to a stiffening layer ( ). The inner stiffening layer ( ) is made of an SMC-material, whilst the outer stiffening layer ( ) is made of a needled, preferably open-celled or porous nonwoven, also suitably impregnated against humidity and dirt. The structure of the carrier layer ( ) and, in particular, the sequence of the layers: skin, honeycomb structure, nonwoven is of particular significance for the mechanical stability of the carrier layer ( ). The carrier layer ( ) is provided with an inner and an outer lining, the inner lining comprising a PU-foam spring layer ( ) and a rubber or latex mass layer ( ). These inner and outer linings, by choice of suitable materials and configurations, can provide acoustically absorbent insulation systems for the vehicle flooring assembly.

Lightweight vehicle flooring assembly

A method for the production of an inherently stable self-supporting composite part for engine hoods for acoustic screening of noises. A prefabricated outer membrane blank part is cut and trimmed to form an outside sheet. This outside sheet is bonded to a prefabricated inside packing to form a self-supporting structure independent of the engine hood. The inside packing is provided with fastener elements and a removable protective film attached to an exposed surface of the packing. A primer is applied to the outside sheet of the self-supporting structure. A lacquer is applied to the primer and the protective film is removed.

Sound-insulating vehicle body part

There is described a sound-insulating power vehicle part which includes a shaped outer sheet and an acoustically effective inside packing which together form an inherently stable lightweight composite part. To obtain this, a thermosetting plastic is used for the outer sheet while the inside packing is formed of a fiber-resin fleece, which is only slightly compacted in an acoustically effective main area and is closely compacted in its stabilizing areas.
