Abstract：

In order to explore the influence of rivet height on the tensile strength of self-piercing riveted joint between carbon/glass fiber resin matrix composite materials (CFRP/GFRP) and AA5754 aluminum alloy, the tensile-shear tests were conducted on AA5754 aluminum alloy self-piercing riveted joint with the rivet height of 7, 8 and 9 mm respectively, and the formed cross section and failure mode were observed. The results show that the higher the rivet height is, the better the formed cross section of AA5754 aluminum alloy self-piercing riveted joint is. The rivet height affects the initial stiffness of CFRP-AA5754 and GFRP-AA5754 riveted joints. When the rivet height is the same, the maximum static load of GFRP-AA5754 riveted joint is about 25% higher than that of CFRP-AA5754 riveted joint, but their difference in energy absorption is small. Furthermore, when the rivet material is the same, the greater the rivet height is, the greater the maximum load mean and the energy absorption capacity of joint are. However, the failure modes of CFRP-AA5754 riveted joint are the separation of composite material plate from the rivet, the fracture of upper plate material filament and the interlaminar cracking, and the failure mode of GFRP-AA5754 riveted joint is the separation of metal plate and rivet.
