摘要
编织复合材料性能预报与材料优化设计研究是编织复合材料研制开发的重要环节。本文在已建立的三维多向编织复合材料单胞几何模型的基础上 ,研究建立了含多相介质单元的有限元分析方法。结合实例预报了碳 /环氧四向编织复合材料的有效性能并和实验结果进行了对比。
Based on the unit cell geometrical model of 3\|dimensional multi\|directional braided composites, the forming method of multi\|phase element stiffness matrix is studied, and the meso\|scopic calculating mechanics analyzing method of 3\|dimensional multi\|directional braided composites is established. The effective mechanical properties of the 4\|directional carbon/epoxy braided composites are predicted and the comparison between the theoretical predictiom and the experimental data is presented.
