    摘要:

    使用Pro/E 5.0构建出一种三维角联锁机织复合材料细观结构模型,利用ANSYS分析侧压载荷下复合材料中纤维与树脂应力应变分布情况,预测复合材料在侧压载荷下的力学行为,并对比复合材料侧压性能。结果表明:复合材料侧压性能表现出各向异性,纬向侧压性能好于经向;复合材料中纤维承载更多的载荷作用,树脂发生更大的变形;轴向平行于侧压方向的纤维承受更大的载荷作用,轴向垂直于侧压方向的纤维承受较小的载荷作用。

    Abstract:

    Mapping software Pro/E 5.0 was used to build structure models of 3D angle-interlock composite in warp and weft directions. Finite element analysis software ANSYS was used to simulate the lateral compressive properties of the 3D composite in warp and weft directions. The mechanical behavior of the composite was predicted by investigating the stress and strain distribution of fiber and resin under lateral compressive loads.In addition,the lateral compressive property between warp and weft directions was compared with each other. Results showed that the lateral compressive property of the 3D composite is obviously anisotropic, behaving as the lateral compressive property in weft direction better than that in warp direction.Fiber made the major contribution for subjecting the load,while the resin made the major contribution for deformation.Fibers parallel to the lateral direction are subjected to larger load,while fibers perpendicular to the lateral direction are subjected to smaller load.
