通过计算机图形建模解决了三维编织复合材料内部编织结构分析困难的问题,从而便于进行下一步编织复合材料力学性能的分析.同时针对三维编织复合材料中目前较为流行的一种编织工艺—四步法,提出了一种定量描述三维编织物内部复杂构造的方法.即首先利用计算机绘制三维实体模型来模拟织物内部各纱线的空间位置,并用动画显示纱线的运动过程,从而能够方便直观地观察到各纱线具体走向,进而通过对已生成的三维实体模型完成简单的操作,来剖析织物结构的内部构造,实现对其内部各纱线的分离、切剖和观察内部纱线间的相对位置关系.并且还验证了传统的几何方法描述中已经提出的一些结论.

A complicated question which structure analysis in Three-Dimension braided composites is solved By modeling computer graphics, then the composites mechanics performance will be expediently analysed. This paper presents a quantificationally descriptive method of complicated fabric structure in Three-Dimension braided composites for the prevalent braided technology-four-step procedure. By emulating the spatial location of optional yarn as computer Three-Dimension model, the yarn trend in Three-Dimension braided composites is shown conveniently and clearly, and every yarn can be separated and dissected for observing relative position by simply operating the completed model. Some presented conclusions of geometrical description are also validated.
