Abstract：

In order to explore the feasibility of electromagnetic riveting (EMR) technology in carbon fiber reinforced plastics (CFRP), the hybrid CFRP- aluminum alloy structures were taken into account. Then, the interference, shear and pull-out properties of electromagnetic riveted joints were studied, and the comparison with traditional quasi-static riveted (QSR) joints was carried out. The results show that the relative interference for EMR structures is more uniformity, and the average value of interference is higher for both Φ4 mm rivet and Φ6 mm rivet. Specifically, they are increased from 4.96% to 5.20% and from 6.85% to 7.85%, respectively. However, the shear properties of electromagnetic riveted joints are greatly improved. For Φ4 mm rivet and Φ6 mm rivet, the maximum shear loads of electromagnetic riveted joints are 19.7% and 5.2% higher than that of QSR joints, respectively. And the pull-out properties are slightly improved. Furthermore, the maximum pull-out loads of electromagnetic riveted joints is 3.9% and 6.6% higher than that of QSR joints, respectively. The results demonstrate that the EMR technology fits for composites connection more.
