The aim of the project is to develop a joining device with an integrated heating unit for joining aluminum alloys with short glass fiber reinforced plastic without an auxiliary joining element. The basis of the investigations is the flat clinch technology, which, due to the favorable triaxial stress state, also enables the joining of brittle materials due to the high hydrostatic pressure and does not require an auxiliary joining element. A heating unit integrated into the tool carrier uses high-frequency heating to generate a defined temperature profile in the plastic that is matched to the forming process. The process design of the joining process and the heating with the aid of numerical methods is intended to ensure that the forming of the plastic in the joining process is gentle on the material. The short glass fibre-filled plastic should be formed as non-destructively as possible without thermally damaging the matrix material, so that the joint strength and reproducibility are maximized.
