| 摘 要： | 为给三维机织正交结构复合材料的力学模拟分析提供一种模型，通过观察3层机织正交结构复合材料预制件的细观几何结构，分析其最小重复单元中纱线间的几何位置关系，探讨细观结构中的几何参数与宏观设计参数的关系。在此基础上，利用Pro/Engineer软件对复合材料预制件进行参数化设计，建立三维机织正交结构预制件的通用几何模型。通过对比制得的三维机织复合材料的实际结构与模型结构以及纤维体积分数，验证了该模型的合理性。

| Abstract: | In order to develop an available model for simulative analysis of mechanical properties of 3D woven orthogonal structure composites, the micro-geometry structure of the preform of three-layer orthogonal woven composite was observed and the geometric positional relationship between the yarns in the least repeating unit of the three-layer orthogonal woven composite was analyzed. Then the relationship between the geometrical parameters of the least repeating unit and the designing parameters was discussed. On this basis, parametric design of the preform of composite material was carried out by using Pro/Engineer software, and a common model of the 3D orthogonal structural preform was established. And then, the rationality of the model was verified by comparing the actual structure, model structure, and the fiber volume fraction. |
