The self-piercing riveting (SPR) single-strap butt joints (butt joint) were fabricated in similar sheets of Al5052 aluminium alloy and 1420 aluminium–lithium alloy. Mechanical characteristics of SPR butt joints of different materials were discussed comparing with their corresponding SPR single-lap joints (lap joint). The effects of the rivet pitch and the strap length on the butt joints of different materials were investigated. Results indicated that the lap joints have better performance in strength and stiffness, while the butt joints have more superior shock resistance capacity. The strap length had some impact on the failure behaviour of the joint but not the joint strength. The load borne capacity of the butt joints was highly dependent on rivet pitch.

自冲铆接（SPR）单带对接接头（对接接头）采用类似的Al5052铝合金板和1420铝-锂合金板制成。讨论了不同材料的SPR对接接头的机械特性及其对应的SPR单搭接接头（搭接接头）。研究了铆钉间距和带子长度对不同材料对接接头的影响。结果表明，搭接接头在强度和刚度方面具有更好的性能，而对接接头具有更好的抗冲击能力。带的长度对接头的破坏行为有一定影响，但对接头强度没有影响。对接接头的承载能力高度取决于铆钉间距。
