摘要
提出一种分析纺织结构复合材料力学性能的模型——纺织几何学模型。该模型由分析单细胞的纤维束几何特征入手 ,考虑纤维束的曲率、非圆形截面形状、纤维纱之间相互纽结等因素 ,建立本构模型。以三维编织结构复合材料为例 ,进行了理论预测并与实验结果进行了比较 ,结果比较满意。
A general Textile geometry modelis presented for the elastic analysis of textile structural composites.The geometrical characteristics of the yarns in the unit cells are considered and based on fiber undulation and continuity in three dimensional space,actual cross sectional geometry of the yarn and the influence of mutual tangle between yarn,the model is established.A unified analytical method and software is obtained by using the model.The theoretical predicted values are compared with the experiments for 3D braid structural composites.The result are fairly good for selected test specimens.
