ABSTRACT:
A composite structure is provided which facilitates the joining of members having different physical properties, and that have sheet portions that lie facewise adjacent to each other. A first sheet-like member (16, FIG. 6 ) of first required properties such as steel which has high strength, is formed with a plurality of recesses (30A, 32A, 84). A second sheet-like member (24) of second required properties such as aluminum which has low weight and corrosion resistance, is formed with upstanding flanges to partially surround the first member. The second member is laid facewise against the first member and locations (26A, 28A, 80) on the second member are pressed into the recesses of the first member to join them. The first member preferably has tapered recesses (30A, 32A) in each of two opposite edges, and also (84) in its bottom face, and the second member has edge portions forming upstanding flanges (26A, 28A). With the first sheet portion received closely between the flanges of the second one, locations along the flanges of the second member are deformed into the edge recesses, while locations along the second sheet portion are deformed upwardly into the recesses in the bottom face of the first member.
