摘　　要：为了进一步深入了解变截面三维编织预制件的研究现状,阐述了变截面三维编织预制件的增减纱原理及原则,分析比较了多种变截面预制体增减纱工艺的优缺点以及新型携纱器的弊端,论述了增减纱工艺对变截面预制件力学性能的影响,并就变截面预制件的研究现状进行了评价,展望了变截面三维编织预制件未来的发展方向。In order to further understand the research status of variable cross - section three dimensional brai- ded preform. The theory .and principle of increasing and decreasing yarn for 3D braided preform with variable cross - section are expounded. Characteristics of various adding - yarn or reducing - yarn techniques and new type of yarn carriers are analyzed and compared. Effects of adding - yarn or reducing - yarn techniques on mechanical properties of the preform are also discussed. The research status of variable cross - section perform is evaluated. Finally development trend is prospected.
