摘　　要：在复合材料承载时变形协调的前提下,采用CAD软件绘制三维织物单元体几何模型,然后导入结构分析有限元软件包,对工程中常用的带衬经三维角联锁结构复合材料的弹性性能进行分析,并将0°和90°方向弹性性能预测值及实验值与取向平均法预测值进行比较。结果表明,采用的有限元方法所得预测值及实验值与取向平均法预测值之间具有很好的一致性。Based on deformation compatibility of the load-bearing composite, CAD software was used for plotting the geometrical model of 3D fabric unit, then FEA （finite element analysis） software was introduced. The FEA software was used for analy- zing elastic properties of 3D angle interlock structure reinforced composite with warp-stuffer. The FEA predicted value and test value of elastic properties of the composite at 0°and 90° were compared with those by orientation average method, and the results show that the FEA values agree well with the predicted values of orientation average method.
