摘要
缝合连接三维编织技术有效地解决了制作复杂形状异型件时存在的局限性。它把三维编织工艺和缝合工艺结合起来,从而满足了工程设计和整体性的要求。本文主要探讨了缝合连接形式、缝合连接工艺参数以及它们对缝合连接强度的影响,并且对缝合连接的基本破坏模式进行了分析。本文为缝合连接三维编织复合材料的结构设计、工程应用和力学性能研究提供了基础依据,同时提出了当前研究中应解决的问题以及缝合连接三维编织复合材料的主要研究方向。
Stitching joint technology effectively solves the limitation of three-dimensional braiding in making preforms of complex shape. This technology combines the three-dimensional braiding process with stitching process to meet the need of engineering design and structural integrity. This paper principally discusses the styles, parameters and their influences on the stitching joint strength, analyzes the breakage modes of stitching joint. It provides basic foundations for structure design, engineering application and mechanical behaviors research of stitching joint 3D braided composites. Meanwhile, it puts forward current problems to be solved and the main research direction in the next few years.
