The invention relates to a double-layered sheet metal with a first layer (5) of sheet metal comprising indented knobs (4I-4IV; 4V-4VII; 4VIII-4XIII), with several of these knobs forming the corner points of a geometrical segment (8I, 8II, 8III) of the first layer (5) of sheet metal, with a second layer (6) of sheet metal which is connected to the first layer (5) of sheet metal in the area of the tips (4a) of the knobs (4I-4IV; 4V-4VII; 4VIII-4XIII), and with a filling (7) made of filling material arranged in the void remaining between the layers (5, 6) of sheet metal. With such a double-layered sheet metal the danger of "total failure" in the case of a load exceeding elastically endured deformation is reduced in that the geometrical segment (8I, 8II, 8III) comprises at least one indentation (10) by means of which any deformation of the double-layered sheet metal caused by a bending load is directed towards the filling (7) in the void. Furthermore, the invention relates to a method for producing such a double-layered sheet metal. |
