COMPOSITE PART CONTAINING METALLIC FOAM

A sandwich component, which comprises at least two massive metallic sheet metal parts located opposite one another and a metal powder layer to be expanded, which is arranged between the sheet metal parts, is shown, in which the sandwich component has additional reinforcing elements in individual cross-sectional areas, and the said reinforcing elements are connected in a positive-locking manner to the expanded metal powder layer surrounding same, and the said metal powder layer is in turn connected to the outer, massive metallic sheet metal parts in such a way that it cannot be detached without destruction.Moreover, a process for manufacturing the sandwich component is disclosed, in which a massive metallic sheet metal part 4, 5 each is provided with a metal powder layer 6, 7; the two sheet metal parts 4, 5 are subsequently arranged one on top of another with the sides provided with the metal powder layer 6 and 7 facing each other, and the sheet metal parts lying one on top of another are then heated up such that a connection which cannot be detached without destruction is established between the metal powder layers 6, 7 facing one another by a heat-induced expansion process.
