摘　　要：纤维增强复合材料胶接结构的疲劳特性与纤维、环氧树脂以及胶黏剂的特性紧密相关,为了开展复合材料胶接结构的疲劳性能研究,本文提出适用于复合材料胶接结构的疲劳分析方法,完成复合材料胶接结构的抗疲劳设计,从复合材料层压板、层间以及胶接界面等研究对象的疲劳特性分析方法入手,全面综述了国内外学者在复合材料结构、金属胶接结构以及复合材料胶接结构的疲劳特性及寿命预测方法等方面的研究进展。结果表明:采用S-N曲线拟合得到寿命预测模型对复合材料胶接结构进行寿命预测是行之有效的,以此为依据开发基于物理机制的有限元寿命预测模型可以对疲劳裂纹扩展及疲劳特性进行分析,对于层间损伤和界面损伤,多采用粘聚区模型进行模拟分析,可以为复合材料胶接结构的疲劳失效分析方法的建立提供指导。Fatigue properties of fiber reinforced composite bonded structures are closely related to the properties of fiber,epoxy resin and adhesive.In order to further study the fatigue properties of composite bonded structures,a fatigue prediction method for composite material bonded structure should be proposed.The research progress on the fatigue characteristics of composite structures,metal bonded structures,composite bonded structures is reviewed in this paper,based on the fatigue characteristics analysis methods of composite material laminates,interlaminar properties and adhesive interface.The results showed that life prediction model based on S-N curve fitting is effective for the life prediction of composite bonded structures.Finite element life prediction model based on physical mechanism can be developed to analyze fatigue crack growth and fatigue characteristics.For interlaminar damage and interface damage,the cohesive zone model is used for simulation analysis,which can provide guidance for the establishment of fatigue failure analysis method for composite bonded structures.
