摘要: 使用三维绘图软件PRO/E 5.0绘制出三维角联锁机织复合材料结构模型,借助有限元软件ANSYS Workbench对该结构模型的弯曲疲劳性能进行分析。在复合材料弯曲静力学分析的基础上,添加疲劳工具对复合材料的抗疲劳性能进行分析,通过复合材料纤维、树脂各自的寿命、损伤分布云图分析复合材料的抗疲劳性能。结果表明:弯曲载荷作用下,复合材料与弯曲压头接触的位置表现出更大的弯曲应力;这些位置在较小循环载荷作用下较早发生破坏;与测试方向平行的纬纱较经纱发生更严重的破坏。

Abstract: 3D angle-interlock composite model was created by PRO/E 5.0 mapping software, bending fatigue resistance performance of the 3D composite model was predicted and analyzed with the help of finite element software ANSYS. Based on the results of static analysis, fatigue tool was added to analyze the fatigue resistance performance. That was analyzed by cloud picture of life and damage of fiber and resin. Results showed that maximum stress was located in the areas nearby the testing tool; earlier damage happened at these areas under the cyclic loading that was not enough to break the composite directly; waft fiber parallel with the testing directioned occur more serious damage.

Key words: 3D composite, angle-interlock, bending fatigue resistance performance, finite element analysis
