| 摘要: |
| 为了建立适用于织物纤维增强复合材料层合板的冲击损伤失效准则,在适用于复合材料单向板低速冲击失效准则的基础上,改进了纤维及基体破坏的失效准则. 对于织物纤维增强复合材料层合板,分别考虑了经向纤维破坏、纬向纤维破坏、基体法向挤压破坏、分层破坏等冲击损伤形式. 使用ABAQUS软件建立有限元模型,结合刚度突然退化模型,通过引入不同孔隙率复合材料的基本强度参数,较为准确地预测了不同孔隙率的织物碳纤维/环氧树脂复合材料层合板的冲击损伤投影面积. |

| Abstract: |
| Based on the failure criterion that is suitable for the undirectional composite laminates, the impact damage of fabric fiber reinforced composites is proposed to improve the fiber and matrix damage failure criterion. The impact damage of longitude fiber failure, latitude fiber failure, matrix crushing and delamination were considered for the fabric carbon fiber reinforced epoxy composites laminates. A finite element analysis model is established by using ABAQUS software combined with the sudden stiffness degradation model. Basic strength parameters of composites are used to evaluate the mechanical properties of CFRP laminates with different porosities. The impact damage area of the fabric carbon fiber reinforced epoxy composites laminates are simulated accurately. |
