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.
