摘要：
The application of hybrid material body structure combined with composite material and lightweight or high strength metal is an important way of automobile lightweight, and the effective connection between composites and heterogeneous materials has become the key link of hybrid material body manufacturing. Self-piercing riveting (SPR) technology, with its high quality and efficiency, shows advantages and good applicability in composite material connection and has received extensive attention and research. Summarizing the research results of composite SPR connection in recent years, it is found that: The strength values of SPR joints between composite materials and aluminum alloy sheets are mostly concentrated at about 4 kN, which is comparable to that of SPR joints between metal plates. The main factors affecting the joint performance are the property of base material, rivet structure, riveting process parameters and service condition, meanwhile, the key points to improve the joint performance are to enhance the strength of the composite sheet, reduce the internal riveting damage and defects of the composite material, and improve the mechanical internal locking combination between the rivet foot and the lower sheet. In addition, when the SPR joint combined with bonding process, its comprehensive performance can be significantly improved. © 2023 Beijing University of Aeronautics and Astronautics (BUAA).
