  复合材料钉群连接是复合材料结构的重要连接形式,也是结构承载的薄弱环节。其失效分析是复合材料结构设计和分析的重要环节。钉群连接的失效分析分为两步:首先进行钉载分配分析,以确定外载荷在各个螺栓的分布情况;然后根据各螺栓承受的载荷,对单个钉孔进行失效评价,其中,挤压和旁路载荷作用下最危险的钉孔处首先失效。因此,深入研究复合材料钉群连接钉载分配测试和预测方法十分必要。

复合材料机械连接结构以其可拆卸、连接可靠、技术成熟等特点而广泛应用于航空航天领域。然而,由于复合材料各向异性、脆性特性以及螺栓连接钻孔导致的应力集中等,复合材料螺栓连接易于发生损伤和失效,是结构的薄弱环节。单钉双剪螺栓连接是一种典型连接形式,其层压板的失效模式主要包含拉伸、剪切、挤压、劈裂和拉脱五种情况。为了更好地发挥复合材料机械连接结构的优良性能,深入研究其失效机理具有重要意义。

碳纤维增强树脂基复合材料(CFRP)结构的胶接修理及接头使用广泛,在面内载荷下的失效机理研究仍不够充分及细致,尤其主承力结构的修理还未展开讨论和研究。因此本文根据一种简化的CFRP斜胶接结构进行了拉伸试验及数值模拟,用于研究楔形挖补修理结构及斜面对接接头的抗拉伸性能。分析了该结构在拉伸载荷下的应变和承载能力。通过显微镜观察了破坏断面,得出了破坏模式。
先进复合材料由于其良好的力学性能而被广泛应用于航空航天领域。在复合材料结构设计中,螺栓连接是连接结构的主要应用形式。但螺栓连接部分也是复合材料整体结构中相对薄弱的环节。为提高复合材料螺栓连接的承载能力、增大其最终失效载荷、发挥其最优力学性能,对螺栓连接结构进行多层次、多尺度的优化设计已经成为当下复合材料研究热点之一。
