复合材料胶接单搭接连接强度与失效模式研究
|
摘要
以Tserpes失效准则及其材料性能退化准则为基础,利用ANSYS建立几何模型进行有限元分析,针对模型进行相应的试验验证,以探究各参数对复合材料胶接单搭接连接强度的影响,并得到不同参数下的胶接失效模式。结果表明:复合材料与复合材料单搭接的强度高于钛合金与复合材料单搭接的强度;随着胶接长度、胶接宽度的增大,胶接接头的连接强度呈现先增大后减小的趋势;同时发现,在静拉伸过程中,钛合金与复合材料单搭接的失效模式主要为胶层的粘附破坏,复合材料与复合材料单搭接的失效模式主要为混合破坏,表现为复合材料紧邻胶层的第一层和第二层发生铺层基体开裂与分层破坏,同时胶层发生部分粘附破坏。
In order to explore the influence of the parameters on the joint strength of adhesively bonded single lap joints,the corresponding finite element model has been constructed using ANSYS. The modified Tserpes failure criterion has been utilized to predict its joint strength. Moreover,the failure mode of the joint with each parameter was simulated visually. The results show that,the strength of the composite-to-composite adhesive joint is higher than the strength of composite-to-titanium alloy adhesive joints. With the process of lap length,lap width increasing,the strength of joint is enhanced obviously first and then decreases. And,in the static tension,the main failure mode of the composite-to-titanium alloy adhesive joint is the adhesive failure. The main failure mode of the composite-tocomposite adhesive joint is mixed failure,which is characterized by the layer peeling and delamination failure of the first layer and the second layer of the composite material immediately adjacent to the adhesive layer,while partial adhesion failure occurs in the adhesive layer.
