摘　　要：介绍了复合材料三种连接方式之一——胶接。对双面搭接接头进行了有限元建模,在不同的高温环境下进行拉伸试验,运用相关的失效准则,分析判断复合材料胶接接头的破坏形式,确定温度对破坏形式的影响。通过试验,验证了分析的正确性,对复合材料胶接接头的强度校核及设计改进有重要的指导作用。One form of connections in composites is discussed in this paper. The finite element model of double lap joints was established. The tensile tests were done at different temperatures,and failure criteria were used to judge the way of destruction in bonded composite joints and understand the influence of temperature on the forms of destruction. The finite element model and analysis were verified by tests. The results can be used for strength check and design improvement of double lap joints.
