This present manuscript complements the work presented in the firs part of the study (Part I) tackling the feasibility of the Friction Riveting (FricRiveting). This paper reports on the thermal history (the process temperature evaluated by thermometry and infrared thermography) and mechanical performance (tensile strength, lap shear strength and microhardness) of polyetherimide (PEI) / aluminium 2024-T351 joints. The results showed average process temperatures within 300ºC to 500ºC. These are values close to the melting temperature of the aluminium rivet and the thermal degradation range of PEI. The high temperatures and shear rate induce the formation of the deformed tip of the rivet (anchoring zone) responsible for the high anchoring efficiency of the rivet, and consequently, excellent mechanical properties of joints. The FricRiveting was demonstrated to be well adequate to hybrid engineering thermoplastic and lightweight alloy joints.
