Abstract

This paper reviews the reported literature on dissimilar (non-matched adherend) adhesively bonded joints (ABJs), currently used bonding processes, and the mechanisms by which these types of joints fail when subjected to structural loading and environmental conditions. Additionally, approaches to improve the performance of dissimilar ABJs, through geometrical and material modifications, are also discussed. Many studies have reported on the strength and failure behaviours of adhesively bonded joints, but of those, few have reported on the performance of dissimilar ABJs. Unlike matched ABJs, the absence of accepted design approaches for dissimilar ABJs arises from their inherent inhomogeneity, which introduces complexities in load transfer mechanisms, in the distribution of stresses through the joint, and in the mechanisms by which the joint ultimately fails. Several authors have proposed approaches to improve the performance of adhesively bonded joints, variously through geometrical or material modification means, but there remains unmet research needs to better understand novel dissimilar ABJ designs.

具有不同粘附体的混合和粘接接头:批判性评论

摘要

本文回顾了有关不同(非匹配被粘物)粘合接头 (ABJ)、当前使用的粘合工艺以及这些类型的接头在承受结构载荷和环境条件时失效的机制的报道文献。此外,还讨论了通过几何和材料修改来提高不同 ABJ 性能的方法。许多研究报告了粘接接头的强度和失效行为,但其中很少有关于不同 ABJ 性能的报告。与匹配的 ABJ 不同,不同 ABJ 缺乏公认的设计方法是因为它们固有的不均匀性,这在载荷传递机制中引入了复杂性,在通过接头的应力分布中,以及关节最终失效的机制。几位作者提出了通过几何或材料修改方法来提高粘合接头性能的方法,但仍有未满足的研究需求,以更好地理解新的不同 ABJ 设计。
