三维编织复合材料中纤维束走向的研究

A Study on Fibre Tows' Orientation for 3-D Braided Composites

本文采用计算机图像分析技术，重点对三维编织复合材料微观结构中纤维束的走向进行了研究、结果表明、在三维编织复合材料中纤维束呈直线状态。并计算了内部编织角与表面编织角的关系式。

In this paper,a computer image analysis technique is developed to study the fiber tows' orientation (FTO) of the micro-structure of 3-D braided composites. The results indicate that FTO is straight in the 3-D braided composites. In addition,inner yarn braiding angle of regular pre forms is expressed. The relation is given between the inner yarn braiding angle and the surface yarn braiding angle.
