摘　　要：在航空航天、汽车等领域中,轻金属-复合材料混合结构的应用逐渐增加,碳纤维增强复合材料(Carbon Fiber Reinforced Poly,CFRP)与铝合金的焊接是亟待解决的难题之一。搅拌摩擦点焊(Friction Spot Welding,FSpW)是一种新型的可用于焊接金属与复合材料的焊接方法。综述近年来关于CFRP与铝合金搅拌摩擦点焊的可行性、影响因素、焊接性能以及接头断裂机理等方面的研究进展,最后展望了未来关于CFRP与铝合金搅拌摩擦点焊的研究热点。Light metal-composite structures are increasingly demanded in a wide range of engineering applications,such as the transportation and aerospace industry. However,the joining of metal alloys and composites is a great challenge. Friction stir spot welding（FSpW） is an alternative joining technology to produce metal-composite joints. This paper summarized on the research progress about the feasibility,factors,weld performance and joint fracture mechanism of FSpW of carbon-fiber-reinforced poly and aluminum alloy Finally,the current problems and issues in FSpW were discussed.
