In contrast to classical joining technologies for composite/metal hybrid structures like bonding and riveting contour joints prove to be a valuable alternative in terms of manufacturing efficiency and mechanical performance. Joining systems with a form closure function enable to pass high loads into rod- and tube-shaped composite structures and are capable of achieving high degrees of material utilization for the fibre reinforced structure. The aim of this paper is to give an overview of the design and the intrinsic processing technology of carbon fibre reinforced polyamide 6 with a multi-scale structured aluminium load introduction element. The presented approach to combine hydroforming of metals with an intrinsic bladder assisted blow moulding process of braided fibre reinforced thermoplastic tape systems enables an industrial scale production of hollow hybrid composite structures with metallic load introduction elements with no need of further trimming or post-processing operations. The process parameters time, moulding pressure and process temperature show a significant effect on the moulding quality of the part and were optimized to consistently produce high-quality CFR-TP parts. Additional investigations addressing the electrochemical compatibility of the joining partners were conducted and a processing suitable surface treatment method to prevent galvanic corrosion of the aluminium load introduction element was determined. Further, the design principles of transferring high loads by multi-scale structured load introduction elements into composite profile structures are numerically examined and design guidelines are given. Finally, an extensive mechanical testing program of CFR-TP tension rods with micro, meso, macro and combined structured load introduction elements was carried out showing the improved uniformity of the load distribution within the interface area and the strengthening effect of multi-scale structuring.
