This paper describes the development of a new hybrid composite for the metal joints of aluminium and glass fibre composite adherents. The aluminium adherend is manufactured using friction stir-formed studs that are inserted into the composite adherend in the through-thickness direction during the composite manufacturing process, where the dry fibres are displaced to accommodate the studs before the resin infusion process. The materials used were AA6082-T6 aluminium and plain-woven E-glass fabric reinforced epoxy, with primary applications in naval vessels. This joining approach offers a cost-effective solution that does not require complicated onsite welding. The joint design was developed based on a simulation test program with finite element analysis, followed by experimental characterisation and validation. The design solution was analysed in terms of the force displacement response, sequence of load transfer, and characterisation of the joint failure modes.
本文描述了一种用于铝和玻璃纤维复合材料被粘物金属接头的新型混合复合材料的开发。铝被粘物采用搅拌摩擦成型螺柱制造，在复合材料制造过程中，这些螺柱沿厚度方向插入复合材料被粘物中，在树脂灌注工艺之前，干纤维被移位以容纳螺柱。所使用的材料是AA6082-T6铝和平纹编织E玻璃纤维织物增强环氧树脂，主要应用于海军舰艇。这种连接方法提供了一种经济高效的解决方案，无需复杂的现场焊接。接头设计基于有限元分析的模拟测试程序开发，随后进行实验表征和验证。从力位移响应、载荷传递顺序和接头失效模式的表征方面对设计方案进行了分析。
