纺织复合材料预制体成形过程纤维束摩擦行为研究进展

预制体是复合材料的增强骨架，由成千上万根纤维束织造而成. 预制体中的纤维束由于织造过程中的交织运动会发生不同程度的摩擦损伤，而纤维的磨损会导致预制体力学性能损失率高达9%~12%. 因此，揭示纤维束在织造过程中的摩擦磨损机理对提升预制体力学性能具有重要意义. 本文中综述了近年来有关纤维束摩擦行为的研究进展：首先，概述纤维束-金属和纤维束-纤维束摩擦测试方法的优缺点；其次，分析得出摩擦角度、摩擦频率、预加张力和法向载荷对纤维束摩擦性能的影响机制；最后，总结纤维束摩擦磨损行为的理论分析模型. 本综述中对复合材料预制体成形工艺设计和纤维束摩擦损伤的量化分析具有指导意义.Preforms, the reinforcing skeletons of composite materials, are woven from thousands of fiber tows. The fiber tows within the preform may sustain friction damage of varying degrees due to interweaving movements during the weaving process, and the wear of fibers will lead to a mechanical property loss rate of up to 9%–12% for the preform. Therefore, revealing the friction and wear mechanisms of fiber tows during the weaving process is of great significance for improving the mechanical properties of preforms. This paper reviews the research progress on the friction behavior of fiber tows in recent years: First, the advantages and disadvantages of fiber tow-metal and fiber tow-fiber tow friction testing methods are outlined; Second, the influencing mechanisms of friction angle, friction frequency, pre-tension and normal load on the friction performance of fiber tows are analyzed; Finally, the theoretical analysis models for the friction and wear behavior of fiber tows are summarized. This review provides valuable guidance for the forming process design of composite preforms and the quantitative analysis of fiber tow friction damage.
