For achieving efficient lightweight materials, automotive development focusses more and more on hybrid plastic structures. In this context target was to combine plastic and steel to develop a cost and weight optimized hybrid structure. Their performance strongly depends on the adhesion between the combined materials. Mechanical interlocking is commonly used for the joining of the two materials. However, an adhesive bonding of the polymer and metallic surface is more effective. Therefore, different kinds of adhesion promotion primers are available. Several of these were tested by SITECH Sitztechnik GmbH and within the project “TRoPHy2” by Salzgitter Mannesmann Forschung GmbH and the project partners. Regarding the tested primer systems, the multilayer film-adhesives by nolax AG showed the best performance. The film-adhesives were developed for hybrid structures for interior parts with decorative applications, for example metal decor parts out of aluminium with a thermoplastic back injection moulding layer.The suitability of these film-adhesives on steel surfaces was proved within a large test program including adhesion, corrosion, forming and other automotive processing steps. Among these tests suitability for large-scale production of film coated steel was also estimated. All tests showed good results.At the opening of the Open Hybrid LabFactory e. V. (OHLF) a first hybrid seat structure, produced by injection moulding, was presented. This structure was validated regarding to function and safety requirements. In view of a large-scale production, first lamination tests were done on the coil coating line of Salzgitter Flachstahl GmbH. A series launch is possible and economic lightweight structures are realizable.
