| 摘 要： | 使用三维绘图软件Pro/E 5.0构建出一种三层角联锁机织复合材料的细观结构模型,借助有限元软件ANSYS对复合材料在剪切力作用下纤维与树脂的应力、应变分布进行数值模拟,并借此分析该复合材料在剪切作用下的力学行为,并预测复合材料破坏模式。结果表明:复合材料在剪切力作用下发生沿剪切力方向程度较均匀的剪切变形;纤维相对于树脂承受更多剪切力作用,产生更大应力,但发生相对较小的应变;纤维中轴向与剪切力方向平行的经纱相对轴向垂直于剪切力的纬纱表现出更大的应力和应变。

| Abstract: | A structural model of three layers angle interlock woven composites, was built by mapping software Pro/Engineer. The distribution of stress & strain on fibers, resin and 3D composites, was simulated and discussed, under shear loading using finite element software ANSYS Workbench. And the failure mode of composites was analyzed. The results show that, uniform shear deformation on the shear direction occur in the composites. The main loads were supported by reinforced fibers and the minor loads were supported by matrix resin. Compared warp yarns to weft yarns, warp yarns axial direction parallel to shear direction show larger stress and strain than those axial direction perpendicular to shear direction. |
