摘要/Abstract

摘要： 提出了一种梳状页型胶接接头结构,基于Hashin失效准则与内聚力模型构建了接头有限元分析模型,设计并制备了页型接头与单搭接接头试件,进行了拉伸试验。结果表明:页型接头的仿真极限载荷为19 666 N,试验均值为16 729 N,误差为14.9%;其失效模式包括胶层内聚损伤和CFRP被粘件撕裂损伤,仿真与试验的失效形貌一致,验证了有限元模型的准确性。与同尺寸单搭接接头相比,页型接头平均失效载荷提升了4.09倍。页型接头通过结构优化实现了胶层和被粘件的等强度设计,可为复合材料轻量化连接提供高效设计方案。

Abstract: A comb-shaped page type adhesive joint structure was proposed to enhance the tensile performance of carbon fiber reinforced polymer (CFRP) connections. A finite element analysis model of the joint was established based on the Hashin failure criterion and cohesive zone model (CZM), while page-type joints and single-lap joints were designed, fabricated, and subjected to tensile tests. Results demonstrate that: the simulated failure load of the page-type joint is 19 666 N, with an experimental mean value of 16 729 N (14.9% deviation). The failure modes include cohesive damage in the adhesive layer and fiber tearing in CFRP adherends, and the consistent failure morphologies between simulation and experiments validate the accuracy of the finite element model. Compared with single-lap joints of the same dimensions, the page-type joint exhibits a 4.09-fold increase in average failure load. Structural optimization of the page-type joint enables balanced strength design between the adhesive layer and adherends, providing an efficient design solution for lightweight composite connections.
