摘　　要：纤维预制体渗透率张量作为复合材料液体成型工艺过程中树脂流动数值模拟的决定性输入参数,与树脂流动以及最终成品质量密切相关,是实现复合材料高质量和大批量制造的关键。本文根据流动状态(饱和或非饱和)、流动维度和测量方向(面内或面外)将渗透率测量技术分类,论述了相应条件下的渗透率测量技术以及研究进展,总结归纳了非饱和流动中流动前沿实时监测技术,分析了造成渗透率测量结果分散性大的影响因素,并阐述解决办法,最后提出未来发展趋势。The permeability tensor of fiber reinforcement,as the decisive input parameter of resin flow simulation of liquid composite molding process,is closely related to the resin flow and final product quality,and is the key to realize the high-quality and large-scale manufacturing of composite materials.In this paper,the permeability measurement techniques are classified according to the flow states(saturated or unsaturated),flow dimensions and measurement directions(in-plane or out-of-plane).The permeability measurement techniques and research progress under different conditions are listed,and the real-time monitoring techniques of flow front in unsaturated flow are summarized.The problems such as different experimental factors and large dispersion of permeability results are analyzed,and the future development trends are discussed.
