2、；考虑缠绕层、编织层进入拉挤成型模具前后的线型变化关系和管道的设计要求，分别设计缠绕线型和编织线型；按设计的线型试制多种规格的复合材料管道，通过对比分析理论纱柬角度与实际测量值，发现同一直径的管道，编织角的误差小于缠绕角的误差，两者均控制在1．5。以内，角度误差率均小于3％，且误差均随管道厚度的增大而减小，管道直径越大，编织角与缠绕角越接近实际值。通过分析管道试件的超声波扫描图，管道无明显缺陷，纱束间无明显细缝，证明设计的纱柬线型变化合理。关键词：复合材料管道；编织一缠绕一拉挤工艺；线型设计中图分类号：TB332文献标识码：A文章编号：1001。3539(2015)09．0060．06Rese
