“…At the same time, the melted resin adhered to the surface of the aluminum alloy, improving the strength of the bonding. It can be judged from the melting of aluminum that the temperature at the interface was close to the melting point of 6061 aluminum alloy, which was higher than the thermal degradation temperature of polyether ether ketone composite (PEEK) resin at 570 °C [ 19 , 28 ]. In addition, the carbon fibers that originally existed in the position of serrated aluminum alloy particles underwent a chemical reaction.…”

Welding and riveting hybrid bonding technology was applied to join 6061 aluminum alloy and carbon fiber reinforced plastics (CFRP). The laser-arc hybrid welding process and stepped rivets were used in the experiments to reduce the impact of the poor heat resistance of composites. The effect of hybrid welding arc current on the formation and mechanical properties of 6061 Al/CFRP joints was studied. Tensile shear load up to 4.65 kN was achieved by adjusting process parameters. The welding process and mode of the fracture were analyzed. The hybrid bonded joint obtained consisted of two parts: a welded joint of Al plate and Al rivet, and a bonded interface between Al plate and CFRP plate. The mechanical properties of the hybrid joint were mainly determined by the Al plate/Al rivet welded joint. The results of the study show that there are three interfacial bonding mechanisms between aluminum and CFRP. In addition to mechanical bonding between the Al plate and CFRP plate, there were also metallurgical bonding of Al-Mg intermetallic compounds with resin matrix and chemical reactions of aluminum with resin and carbon fibers at the interface, which could improve the mechanical properties of the joints.

“…The hybrid joints of 5052 aluminum alloy and CFRP were fabricated by friction stir spot welding. By optimizing the welding parameters, the ultimate tensile shear load reached 2690 N [ 19 ]. Besides, the ultrasonic spot welding process was also applied to join 5754 aluminum alloy and carbon fiber reinforced epoxy.…”

Polyoxymethylene (POM), as an energy‐saving material, is widely applied in the manufacturing field. Yet, research on the rectangular clinching process between metal and POM sheets is still lacking. In this paper, the rectangular clinching process for POM and Al5052‐H32 plates was investigated. The feasibility of the metal–polymer hybrid component had been analyzed in terms of diverse forming forces and diverse joint layout angles, respectively. The mechanical characteristics were appraised by the lap‐shear test. The failure modes of rectangular clinched joints produced under diverse forming conditions had also been analyzed. The results showed that the optimal forming force of rectangular clinched joints was 14 kN, in which the lap‐shear strength was 1090 N. Furthermore, the rectangular clinched joints produced under the joint layout angle of 90° could withstand the maximum lap‐shear load (1415 N) under the optimal forming force. The failure mode was the separation of two plates and the fracture of the bridge structures.

“…The investigation of suitable low-heat joining methods for hybrid joints such as for example ultrasonic welding (USW) [6][7][8], friction stir spot welding (FSSW) [9], or adhesive bonding [10] is not the only engineering challenge. Although the joining technology of FSSW can produce a favorable mechanical interlocking between aluminum and loadbearing fibers, damage to the CFRP laminate due to fiber fracture and delaminations caused by the process was observed [11]. Adhesively bonded joints consisting of aluminum and fiber-reinforced plastics rely on additional surface pre-treatment processes and require long process times for curing [12].…”

Ultrasonically welded hybrid aluminum/fiber-reinforced PEEK joints were analyzed non-destructively with an X-ray microscope. The potential and limitations of the technology as a non-destructive testing method were investigated. For a quantitative evaluation, joints with suitable and unsuitable parameters were compared. For a further comparison, geometric modifications of the joining partners were made, and the influence on the structure and process variation of the resulting hybrid joints was examined on a microscopic level. By using a tool for 3D segmentation of the composition of the joining zone, quantitative information on volume-specific proportions could be obtained and compared in relation to each other.
