摘要：
Fiber reinforced composites are widely used in aerospace and other engineering fields. Delamination is the main damage form in fiber reinforced composite laminates and also has been one of the focuses of composite mechanics. In this paper, the research achievements about the delamination in fiber reinforced composites at home and abroad are systematically surveyed from three aspects: the experimental research, mechanical model, and numerical simulation. The fracture toughness test methods and theories for modes I, II, and mixed I/II delamination of unidirectional composites and experimental researches on delamination of multidirectional composites are introduced. The fiber bridging model, the delamination growth criterion, and the fatigue delamination model for characterizing and evaluating the delamination behavior are concluded. In addition, the research status of the numerical simulation on delamination carried out by the Cohesive Zone Model (CZM), the Virtual Crack Closure Technique (VCCT) and the Extended Finite Element Method (XFEM) are expatiated. Finally, the future development directions of delamination in composite materials are prospected. © 2019, Press of Chinese Journal of Aeronautics. All right reserved.
