摘要: 本文发展了一种复合材料层压板冲击损伤数值模拟分析方法,建立了低速冲击问题的分析模型,该模型考虑了纤维损伤、基体损伤以及层间损伤等失效模式,采用基于物理失效模式的Puck失效准则预测损伤起始以及基于断裂应变能的刚度退化方式预测损伤演化过程。开展了T300、T700以及T800等多种纤维和树脂匹配层压板的抗冲击性能试验研究,获得了纤维和树脂性能对层压板抗冲击性能的影响规律。通过仿真结果与试验结果对比,表明所发展的复合材料层压板低速冲击损伤数值分析方法具有较高精度。

Abstract: A numerical simulation analysis method for impact damage of composite laminates was developed, and an analysis model for low-velocity impact was established. The failure modes such as fiber damage, matrix damage, and interlayer damage were considered in the model, Puck failure criterion based on physical failure modes was adopted to predict the damage initiation and the stiffness degradation method based on the fracture strain energy was used to predict the damage evolution process. The impact resistance tests of T300, T700 and T800 carbon fiber reinforced laminates were carried out, and the law of the influence of fiber and resin properties on the impact resistance of laminates was obtained. The comparison between simulation results and test results shows that the developed numerical analysis method for low-velocity impact damage analysis of composite laminates has high accuracy.

Key words: composite laminates; low-velocity impact; failure criteria; progressive damage; finite element analysis
