Abstract Adhesive bonding is one of the dominant joining technologies in Design for Assembly to obtain innovative engineering products with complex geometries. These permanently bonded joints could be disassembled for repair purposes using the thermo-mechanical debonding technique to salvage the high-cost composite components without any damage. In this work, the temperature dependent storage modulus, loss modulus and tensile properties of the bulk modified epoxy film adhesive were measured through instrumented tests. Glass fibre reinforced composite and Ti–6Al–4V alloy sheets were bonded with the modified epoxy film adhesive and the floating roller peel performance was studied as a function of temperature to understand the load-displacement and failure mechanisms for generating a debonding map. The debonding region was identified in the temperature range between 1.17 T g and 1.33 T g. The knock-down in storage modulus and initial peel load exhibited a similar trend with respect to the temperature.

修复复合金属粘接接头的热机械脱粘图

摘要 粘接是装配设计中的主要连接技术之一，以获得具有复杂几何形状的创新工程产品。这些永久粘合的接头可以拆卸以进行维修，使用热机械脱粘技术来挽救高成本的复合材料部件而不会造成任何损坏。在这项工作中，通过仪器测试测量了本体改性环氧薄膜粘合剂的温度相关储能模量、损耗模量和拉伸性能。玻璃纤维增​​强复合材料和 Ti-6Al-4V 合金板与改性环氧薄膜粘合剂粘合，研究浮动辊剥离性能作为温度的函数，以了解产生脱粘图的载荷-位移和失效机制。在 1.17 T g 和 1.33 T g 之间的温度范围内确定了脱粘区。储能模量和初始剥离载荷的下降在温度方面表现出类似的趋势。
