Analysis on tensile properties and influence factors of composite hybrid joints

  • 摘要: 胶螺混合连接设计适当,能够提高结构的连接效率.针对复合材料胶螺(螺钉)混合连接结构中存在的分析与设计问题,在ABAQUS软件平台上建立了损伤累积三维有限元模型,其中考虑了胶层物理非线性以及非线性接触等问题,连接结构拉伸强度及损伤破坏过程的计算结果与试验结果基本吻合,证明了所建模型的有效性.在此基础上,研究了复合材料层合板端头翻边、胶层厚度、胶层韧性以及接触面摩擦系数等因素的影响.结果表明:复合材料层合板端头翻边对混合连接结构具有增强作用,能够提高结构的拉伸强度;韧性胶层能够提高结构的拉伸强度,但胶层厚度对结构的强度基本没有影响;螺钉杆与连接孔接触面间摩擦系数越大,连接结构的拉伸强度越高.
