A novel joining technology was applied to join Fiber Reinforced Polymer (FRP) and AZ31B Mg alloy, which combined the laser-arc welding source and riveting joining methods. The design idea of the stepped rivet was proposed. The weld morphology, mechanical properties, microstructures of welds under two different rivet structures were investigated. FRP and AZ31B Mg could be joined successfully by the new hybrid joining method when it used two different structural rivets. The maximum tensile shear load of the joint under stepped rivet of small size was only 800 N, while that of the joint under stepped rivet of the larger size could reach 1419 N, nearly 90% of that of FRP. There was no reaction between the FRP plate and AZ31B rivet. While the magnesium elements and aluminum elements diffused and reacted with other elements in the FRP plate/AZ31B plate interface.
一种新型连接技术被应用于连接纤维增强聚合物（FRP）和AZ31B镁合金，该技术结合了激光电弧焊源和铆接连接方法。提出了阶梯铆钉的设计理念。研究了两种不同铆钉结构下焊缝的形貌、力学性能和微观结构。当采用两种不同结构的铆钉时，新的混合连接方法能够成功地连接FRP和AZ31B镁合金。小尺寸阶梯铆钉连接的接头最大拉伸剪切载荷仅为800N，而大尺寸阶梯铆钉连接的接头最大拉伸剪切载荷可达1419N，接近FRP的90%。FRP板与AZ31B铆钉之间没有反应。而镁元素和铝元素在FRP板/AZ31B板界面处与其他元素发生扩散和反应。
