Abstract: A roof liner includes a core layer, a reinforcement layer arranged on at least one side of the core layer, and a decorative layer facing a passenger compartment. The reinforcement layer is formed from at least one plastic matrix and fibres. The core layer is formed from a foam material. The foam material and the plastic matrix present at least one polyolefin. The polyolefin of the foam material is polypropylene and the fibres are arranged non-directionally in the plastic matrix.

Abstract: A fixing member (1) designed for at least partially interlocking axial securement in a solid body (4) by means of an initially fluid setting material (2) introduced into a blind borehole (3), and is intermediately mechanically fixed and adjustable. The fixing member (1) is a peripherally closed medium to thickwalled tubular member (5), at least in part radially deformed and of uniform wall thickness having an axial passageway (6) extending through it.

Abstract: In a thermal shield for components made of thermoplastics, for the automotive industry in particular, an aluminium layer 2 is connected with the component to be protected, which serves as a carrier 1 for the thermal shield H, by means of a thermoplastic coating 3 in the region of the heat source. It is recommended to dispose the thermal shield H not only in the immediate region of heat source 4, but also, on the component, in the area up to a lateral spacing B from the heat source that the aluminium layer 2 may dissipate heat outwardly, i.e. outwardly from the region of thermal shield 4 to a cooler region.

Abstract: A device for absorbing and/or damping sound waves has a system for damping and/or silencing sound waves provided with a thin vibratory layer (1) on the side facing the sound waves. In order to improve sound damping and silencing properties, even during a prolonged use with concomitant exposure to strong heat, the thin vibratory layer (1) is made of aluminum or an aluminum alloy and is 0.004 to 0.35 mm thick.

Abstract: In a so-called “hollow chamber absorber” comprising chamber-shaped intermediate cavities (7) between a supporting body (1), spacers (2) and a covering layer (5) acting as a covering unit (11), simultaneous deformation and connection of the covering layer (5) with the edge (4) of the supporting body (1) and the open front ends (3) of the spacers (2) of the preformed basic constructional unit (10) occur by using a stamp (8) whose front face (9) is configured according to the final state of the covering unit (11) on the basic constructional unit (10).

Abstract: A layered absorber for absorbing acoustical sound waves comprising a plurality of layers with at least one layer being spaced apart from another layer by spacers, and at least one layer having a thickness between 0.
