Multi-material solutions are a promising approach of using thermoplastic matrices for an increasing number of structural applications or further reducing the component weight of existing thermoplastic solutions. These materials are based on a mixture of materials, with the individual materials employed in the particular place where they offer the most benefit. One option to locally reinforce thermoplastic structural parts is tape laying of pre-impregnated UD tapes. The laying process must be automated and material throughput must be sufficiently high. When processing pure fabric structures, the high fiber content of unidirectional tapes means a restriction to formability and flowability. The Fraunhofer ICT has undertaken research aimed at the development of a battery protective casing from a multi-material based on D-LTF, customized local continuous fiber structures and intrinsic metal inserts. A strategy aimed at recyclability of multi-material components must be adapt ed or developed.
