In this paper, fatigue life of extruded aluminium single lap joints, both by self-piercing rivet (SPR) and by hybrid joining (Adhesive-SPR), were characterised based on the quasi-static and fatigue tests. The rivet tail pull-out fracture occurred in the SPR joint specimen under the quasi-static tensile test because the peel stress caused the rivet to separate from the joint. Therefore, adhesive joining was considered to effectively prevent the rivet in the joint specimen from separation. As a result, 68% higher tensile strength of the hybrid joint specimen was observed, compared to that of the SPR joint specimen. From the fatigue tests, the fatigue limit load of SPR joint specimen was found to be 4.8 kN i.e.35% of tensile strength load. The fatigue limit load of the hybrid joint specimen was revealed to be 5.6 kN, i.e., 20% of tensile strength load. Over the fatigue limit load conditions, fracture in base material was shown in the case of SPR joint specimen. Also, fractures in base material and transient failure in adhesives were observed in hybrid joint specimen.
