Friction Spot Joining (FSpJ) is an alternative technique for joining metal-composite lightweight structures. The current PhD work was devised to understand the fundamentals of this new joining technology. The process was optimized for the selected joining parts (aluminum alloy 2024-T3 and carbon-fiber reinforced poly(phenylene sulfide)) and the relation between process parameters (heat input), microstructure and mechanical properties of the joints was established. Further, different analytical techniques were employed to investigate the influence of various aluminum surface pre-treatments on the bonding mechanisms and mechanical performance of single lap shear joints. The durability of FSp joints, under accelerated aging conditions, and their fatigue behavior were also studied in this work.
