    (54) Anchor-bonded composite structures and method of production thereof


    (57) An anchor-bonded composite plate is produced by forcing anchor parts (6) of a cladding plate (2) into corresponding anchor cavities (5, 5a) with overhanging lips in a base plate (1) with sufficient force to plasticly deform the anchor parts and cause the same to fill the anchor cavities, thereby forming a positively locked anchor bond (7). The cladding plate (2) and the base plate (1) may be made of an aluminum alloy and a hard steel, respectively. The composite plate (8, 8a, 8b, 8c) thus produced is applicable as a reaction plate for a linear motor vehicle and as tank material of an LNG tanker.
