摘　　要：根据实际三维机织复合材料预制件的织造参数,借助参数化三维建模软件PRO/E 5.0,基于三维机织物织造角构建了三维机织复合材料单胞模型。采用ANSYS Workbench有限元软件分析了基于复合材料单胞结构模型的经向拉伸性能,考察了拉伸应力、拉伸应变在增强体和树脂基体中的分布情况,分析了织造角对复合材料经向拉伸行为的影响。结果表明:随织造角增大,三维机织复合材料单胞模型沿经向的拉伸应力、拉伸应变逐渐增大;三维机织复合材料受拉伸时纤维承受主要载荷。复合材料增强体中,轴向存在与载荷方向平行分量的经纱相较于轴向垂直于载荷方向的纬纱承载更多的载荷作用。Three unit-cell models of 3 D angle-interlock composite were created by PRO/E 5.0 mapping software. Tensile properties in warp of three unit-cell models were analyzed by finite element software ANSYS. The stress and strain distribution of fiber and resin matrix were investigated in order to analyze the influence of weaving angle on tensile properties of composite unit-cell models. Results showed that tensile stress and strain in warp of three unit-cell models increased with the increased of weaving angle of composite. Compared to the resin matrix, fibers made the major contribution to subject the tensile loading. Compared to the warp and weft yarns, yarns whose component of axial direction parallel to the loading direction subjected the more major loading than whose axial direction perpendicular to the loading direction.
