复合材料三维编织结构的单元体模型

UNIT CELL GEOMETRY OF 3 D BRAIDED STRUCTURE OF COMPOSITES

复合材料三维编织结构技术是国外八十年代发展起来的高新纺织技术。三维编织结构复合材料是一种新型结构形式的复合材料，它具有优良的抗冲击损伤性能、力学性能和耐烧蚀性能。本文讨论了三维编织结构的单元体模型，推导出有关参数之间的数学关系。

The 3 D braiding technique for composites is a new textile technology developed in the United States in the 80s. The composite of 3 D braided structure is a new kind of composites. Its shock damage resistant property, mechanical property and fire resistant property are fairly good. In this paper, the unit cell geometry of the 3 D braided structure of composites was discussed and the relationships of the structural parameters were established.
