摘要/Abstract

摘要： 为了探究不同搭接材料对胶接接头力学性能和失效机理的影响,本文分别利用内聚力模型(CZM)和Hashin失效准则对胶黏剂和碳纤维增强树脂(CFRP)复合材料层合板进行建模。通过对文献中提取的CFRP层合板胶接接头试验进行模拟,验证了模型准确性。此外,在已验证模型的基础上建立同种材料(CFRP、钢板、铝板)和不同种材料(CFRP/钢板、CFRP/铝板)单搭接胶接接头拉伸数值模型,分析了拉伸损伤和胶接接头不同部位刚度退化特点。结果表明,随着胶接长度的增加,所有搭接接头极限荷载均呈增加趋势;钢板和铝板与CFRP混合搭接时,由于钢板强度比铝板强度高,使得铝板混合搭接有更大的拉伸应变和剥离应变,故而相比于铝板混合搭接,钢板混合搭接的极限荷载更高;胶接接头在加载过程中不同搭接材料会影响胶层和CFRP层合板起始损伤。本文通过对不同搭接材料胶接接头的研究,为胶接接头设计提供了依据。

Abstract: To explore bonding material type on the mechanical behavior and failure mechanism of adhesive joint, cohesive zone model (CZM) and Hashin failure criteria were used to model adhesives and carbon fiber reinforced polymer (CFRP) composite laminates, respectively. The accuracy of the model is verified by the simulation of the CFRP laminate bonding joint test,which extracted from the literature. In addition, based on the verified model, the tensile numerical models of the single-lap adhesive joint with the same material (CFRP, steel plate, aluminum plate) and different materials (CFRP/ steel plate, CFRP/ aluminum plate) were established, and the tensile damage and stiffness degradation characteristics of different parts of the adhesive joint were analyzed. The results showed that the ultimate load of all lap joints increases with the increase of bond length. When steel plate and aluminum plate were lapped with CFRP, the strength of steel plate is higher than that of aluminum plate, resulting in greater tensile strain and stripping strain of aluminum plate for hybrid lap joints. Therefore, the ultimate load of steel plate mixed lap is higher than that of aluminum plate. The initial damage of adhesive layer and CFRP laminate was affected by bonding material type during loading. This paper provided the basis for the design of the adhesive joint by studying the adhesive joints of different bonding materials.
