摘　　要：随着轻量化结构需求的不断增长,复合材料在航空、船舶、汽车、建筑、体育器材等领域中的应用越来越广泛。复合材料的连接方式主要有机械连接和胶接连接两种,而胶接连接作为一种高效、可靠的连接方式,在复合材料的连接中尤为重要,是不可或缺的一部分。胶接接头在高承载结构中的广泛应用,增长了对其强度更高、寿命更长、成本更低的需求。本综述通过回顾提高复合材料胶接接头强度的研究进展,讨论并比较现有复合材料胶接结构的几何优化方法,综合分析各几何因素对胶接接头强度的影响,分类列举了不同胶接接头的整体和局部结构设计优化技术,分析了各优化技术改变接头受力方式和应力分布,降低胶接结构中的应力集中程度,进而提高胶接接头的强度的作用和机制。最后,对这些几何方法的突出特点以及局限性进行总结,以提高胶接接头连接效率,拓展胶接接头应用领域,推动复合材料连接技术的发展。With the growing demand for lightweight structures,composite materials are increasingly used in aviation,shipbuilding,automobiles,constructions,sports equipment and other fields.The connection methods of composite materials mainly include mechanical bonding and adhesive bonding.As an efficient and reliable connection method,adhesive bonding is particularly important in the connection of composite mate-rials and is an indispensable part.Due to the widespread use of adhesive joints in highly load-bearing structures,there is a growing demand for higher strength,longer life,and lower cost of these joints.By reviewing the latest research progress in improving the strength of composite adhesive joints,this summary discussed and compared the geometric optimization methods of existing composite adhesive structures,comprehensively analyzed the influence of various geometric factors on the strength of adhesive joints,including optimizing the overall and local structural design of adhesive joints,adjusting the stress mode and distribution of joints,reducing stress concentration in adhesive structures,and thereby improving the strength of adhesive joints.Finally,summarizing the prominent characteristics and limitations of these geometric methods to improve the efficiency of adhesive joint.This paper is helpful to expand the application of adhesive joints,and promote the development of composite material connection technology.
