Hybrid bolted/bonded joints may have the advantages of both mechanical and adhesively bonded joints or disadvantages, which depends entirely on reasonable design. The design of the hybrid bolted/bonded joint is a complex issue, which is related to the material properties of the connected parts and adhesive layer, the number and size of the bolt, and the geometrical characteristics of the joint. Furthermore, the secondary bending in the single-lap joint and the bypass load in the multirow bolted joint to increase the complexity of the problems. Therefore, detailed tests and adequate data are essential to do further research on the mechanical behaviors of bolted and hybrid bolted/bonded composite joints, especially for the joints of bismaleimide resin composite. An experimental parametric study was carried out to reveal the effect mechanisms of different configurations on the mechanical properties of bismaleimide resin composite joints in this study. Single-lap bolted and hybrid bolted/bonded composite joints were focused on and their mechanical behaviors were discussed. According to the investigation of experimental analysis, some useful conclusions have been deduced, which are helpful for the design of bolted and hybrid bolted/bonded composite joints.

螺栓和混合螺栓/粘合复合接头的详细实验参数分析

混合螺栓/粘接接头可能具有机械接头和粘接接头的优点或缺点，这完全取决于合理的设计。混合螺栓/粘结接头的设计是一个复杂的问题，它与被连接部件和粘合剂层的材料特性、螺栓的数量和尺寸以及接头的几何特征有关。此外，单搭接接头中的二次弯曲和多排螺栓接头中的旁路载荷增加了问题的复杂性。因此，详细的测试和足够的数据对于进一步研究螺栓和混合螺栓/粘合复合材料接头的力学性能至关重要，特别是对于双马来酰亚胺树脂复合材料的接头。在这项研究中，进行了一项实验参数研究，以揭示不同配置对双马来酰亚胺树脂复合材料接头力学性能的影响机制。重点关注单搭接螺栓和混合螺栓/粘合复合接头，并讨论了它们的机械性能。根据实验分析的调查，得出了一些有用的结论，这些结论有助于螺栓和混合螺栓/粘结复合接头的设计。
