摘要
在确立三维四向编织复合材料数字化单胞力学分析模型的基础上,运用均匀化方法对三维编织复合材料的等效弹性性能进行了分析计算,并讨论了编织角和纤维体积含量对此材料等效弹性性能的影响.
By analyzing the microstructure, the digitized cell model of three-dimensional four-directional composites is established, then the mechanic properties of three-dimensional four-directional composites are calculated by the digitized cell-based finite element method （DCB-FEM , and the influence of the braiding angle and the fiber volume fraction is discussed.
