Experimental and Computational Analysis of Multi-Spot Welded Hybrid Al/CFRP-Structures on Component Level


  • The financial support of the German Research Foundation (DFG) in the framework of the research unit 524 “Manufacturing, Characterization, and Simulation of Welded Lightweight Structures of Metal/Fiber-Reinforced Polymer Composites” at the University of Kaiserslautern is gratefully acknowledged.




Ultrasonic and induction welds are performed to realize aluminum alloy/carbon fiber reinforced polymer (CFRP) – joints on component level. A demonstrator geometry derived from a possible application is chosen and different spot arrangements are manufactured tested and analyzed at variable testing velocities. Demonstrators are modeled in ABAQUS and FEM simulations are validated with mechanical experiments in order to investigate and explain ultrasonic welded demonstrator behavior and failure progress.
