Influence Of Textile Process Parameter On Joint Strength For Integral CFRP-Aluminum Transition Structures

With increasing application of hybrid structures a novel joining technology is required in terms of lightweight design. For joining CFRP (carbon fiber reinforced plastics) and metal components in load application zones, the conventional method of riveting is often applied, which is not suitable to the material. Within the investigations of the research group “Schwarz- Silber” (FOR1224) funded by the DFG (German Research Foundation) novel transition structures for aluminum-CFRP joints are investigated with view to weight, strength and a lean integral structure. This paper deals with the influence of the textile process on the joint strength. The process parameter pretension, which is defined by the manufacturing process of loop connections for aluminum-CFRP joints, is identified. A suitable material combination for the loop is determined and the influence of the loop's pretension on the joint strength is analyzed.
