In a thermal shield for components made of thermoplastics, for the automotive industry in particular, an aluminium layer is connected with the component to be protected, which serves as a carrier for the thermal shield H, by means of a thermoplastic coating 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 , but also, on the component, in the area up to a lateral spacing B from the heat source that the aluminium layer may dissipate heat outwardly, i.e. outwardly from the region of thermal shield to a cooler region.

Thermal shield for components made of thermoplastics

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 (,) 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 (,) is made of aluminum or an aluminum alloy and is 0.004 to 0.35 mm thick.

Device for absorbing and/or damping sound waves

In a so-called &ldquo;hollow chamber absorber&rdquo; comprising chamber-shaped intermediate cavities (,) between a supporting body (,), spacers (,) and a covering layer (,) acting as a covering unit (,), simultaneous deformation and connection of the covering layer (,) with the edge (,) of the supporting body (,) and the open front ends (,) of the spacers (,) of the preformed basic constructional unit (,) occur by using a stamp (,) whose front face (,) is configured according to the final state of the covering unit (,) on the basic constructional unit (,).

Absorber to absorb acoustic sound waves and method for its production

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 0.01 and 5 mm, such spacers being spaced apart from each other between the layers such that gas-filled chambers are formed, wherein the chambers form resonance chambers for acoustic sound waves by tuning the mass-spring pairs of the resonance chambers such that one maximum per mass-spring pair appears in the absorption curve, and wherein a multiple of parallel resonance chambers of a variety of different dimensions of the parallel resonance chambers are formed by varying at least one of the lateral dimensions of the parallel resonance chambers, the densities of the materials of the walls of the parallel resonance chambers, the thicknesses of the walls of the parallel resonance chambers, the rigidity of the materials of the walls of the parallel resonance chambers, the thicknesses of the walls of the parallel resonance chambers and the heights of the parallel resonance chambers in order to reach different sound absorptions in the respective absorption spectra.

Layered sound absorber for absorbing acoustic sound waves

A sound-absorbing cellular component is produced in multiple-chamber array, using a grid of spaced elongate rods, and by engaging to the rods of said grid a foil of deformable sheet material which is then drawn by deformation through spaces between rods, to thereby define adjacent partition walls of adjacent chambers. Various embodiments are described, involving retention and/or removal of the rods, and/or involving application of one or more insulating or finishing materials continuously over outwardly facing bottoms of the chambers of the array.
