Abstract: A method for producing composite bodies having at least one outer layer of a non-foaming powder and a metal foam layer. In one embodiment, the powder layers are rolled separately from one another, then the rolled parts are put one over the other in a predetermined number of rolled powder layers; optionally, they are rolled together again, and thereafter, the metal foam layer is foamed by heating to produce a layer arrangement. Alternatively, the powder layers are formed one on top of the other to form a layer arrangement that is then rolled prior to foaming.

Abstract: The invention relates to the production of forms or similar from foamed metal based on aluminum or other metals. Semi-finished product bodies or similar consisting of a foamable semi-finished product material obtained by compacting a mixture of at least one matrix metal powder and at least one expanding agent which releases a foaming gas are placed into a foaming mould or similar where they are geometrically arranged in the desired manner and then heated to a temperature in the range of melting temperature of the matrix metal. Once the mould has been filled, the foaming process is concluded and the resulting foamed metal forms are shaped out.
