Abstract: A process for joining components made of metal, in particular aluminum and aluminum alloys, is such that a thermally-curable (hardenable) adhesive is deposited between the close-fitting surfaces of the components that are to be joined, and one of the outer surfaces neighboring the said close-fitting surface of one of the components is radiated with infra-red radiation in order to cure the adhesive. At least the outer surface to be radiated is provided with a pattern that roughens that surface. By reducing the reflectivity of the roughened surface the capacity to absorb infra-red radiation is increased. A preferred application for the process is in the adhesive bonding of shaped parts, especially body sheet in automobile manufacture.

Abstract: A thin, plastically formable composite laminate features at least one metallic outer layer (14) and a core (10) of thermoplastic plastic. The metallic outer layers (14) exhibit a flat stress-strain curve which is similar to that of the plastic core (10) and is achieved by specific types of aluminum alloys and by specific alloy treatments. The, preferably 1.5-2.5 mm thick, composite laminates are employed for the manufacture of shaped parts in light weight constructions, especially in automobile, equipment and architectural applications.
