| 摘 要： | 基于三维全五向矩形编织工艺的携纱器运动规律,系统研究了三维全五向编织复合材料的纱线空间运动方式、纱线间交织结构形态,建立了三维全五向编织结构各区域的单胞几何模型,推导了编织角等工艺参数与各单胞结构参数间的数学关系,计算了纤维体积分数的预测值,并与实测值相比误差较小,表明所建模型较为合理、准确.

| Abstract: | According to the mapping relationship between the movement traces of yarns' carriers on the braiding machine bed,the spatial traces and configurations of interior braiding and axial yarns were systematically studied,the unit cell models of different regions of 3D full 5-directional braided composite were also established,then the mathematical relationship between the process parameters and the microstructure of the unit-cells could be obtained.The predictions of the fiber volume fractions of 3D full 5-direc... |
