Method of filling cavities in workpieces or semi-finished products and structural components parts for mounting on or in a motor vehicle

摘要

Method for filling cavities in workpieces or semi-finished products is provided, in which thermally foamable powdered carbon is added in fixed locations into the cavity to be filled and is heated together with the workpiece or semi-finished product in such fashion that the powdered carbon swells and fills the cavity as carbon foam, with the particles of powdered carbon in the delivered state being smaller than after foaming. A structural component is formed, especially a workpiece or semi-finished product for mounting on or in a motor vehicle body, having an enclosed chamber in which thermally foamable powdered carbon is added in a fixed location, with the powdered carbon being heated together with the structural element to swell the powdered carbon and form carbon foam.
