摘要: 编织复合材料因其预成型过程自动化程度高、织物整体性好、可近净成型、结构设计灵活等优势,结合树脂传递模塑(RTM)、真空辅助树脂浸渍(VARI)等液体成型工艺可实现异型管类复合材料结构的快速低成本制备,是未来低成本复合材料发展的一个方向。本文对二维三轴编织复合材料的结构特点、国内外应用情况进行了介绍,并结合实际工程案例,阐述了典型二维三轴编织复合材料基本力学性能及典型复合材料变截面筒体的研制过程,验证了其工程应用的可行性。

Abstract: Owing to the advantage of high automation, excellent integrity, neat-shaping and flexible designability, braiding technology can be used to fabricate complex composite tubes by typical liquid composite molding methods such as Resin Transfer Molding (RTM) and Vacuum Assisted Resin Infusion (VARI). Braided composites are now becoming a new trend of low-cost composites in the future. In this paper, the features and application of 2D triaxial braided composites (2DTBCs) are introduced. Meanwhile, typical 2DTBCs were fabricated by RTM process,and the basic mechanical properties of the composites were investigated. The results show that the performances of 2DTBC depend on the braiding angle. And the damage area of 2DTBCs after impact was much smaller than the classical laminate composite because of much effective force transferring routes of the fibers in the interfaced braiding structure. The development of a typical hollow composites barrel by braiding and RTM process verified the engineering feasibility of this method.
