三维编织复合材料中纤维束横截面形状的研究

STUDY ON FIBER TOWS' CROSS-SECTION IN 3-D BRAIDED COMPOSITES

摘要: 采用计算机图象分析技术,重点对三维编织复合材料微观结构中纤维束的横截面形状进行了全面的研究。结果表明:在复合材料的内部、边部和角部,纤维束的横截面形状是不同的。并初步探讨了纤维束横截面面积的变化与花节长度的关系。

Abstract: A computer image analysis technique is used to study the fiber tows' cross-section (FTC) in 3-D braided composites. The results indicate that FTC in the center, side and corner of 3-D braided composites is different. The changing period of cross section areas is related to the pitch length.
