摘要

摘要: 根据三维编织的主要工艺, 系统地分析了三维七向编织物纱线的面内和空间运动规律。在此基础上,建立了能反映其基本结构的几何单胞模型, 并推导了编织参数之间的数学关系, 为进一步分析三维七向编织复合材料的力学性能奠定了基础。

Abstract: The planar and spatial yarn paths were analyzed systematically based on a 3D braiding process. A geomet ric unit cell model of the three-dimensional and seven-directional braided composite is established to describe thebasic st ructure , and the relationship between braiding parameters is deduced. This paper proposes the base for theanalysis of the mechanical properties of 3D and 7D braiding composites.
