摘　　要：为研究大丝束碳纤维经编织物的渗透行为,采用单向法对不同织物铺层数和缝编结构的碳纤维预制体进行渗透率的测试。实验结果表明:织物铺层数量直接影响预制体的灌注时间,预制体的有效流道数量越多,树脂流动性越好,渗透率越大;对于缝编结构不同的织物,通过相同铺贴方式制成的预制体,纤维束平行流道数量较多的预制体,渗透率相对较大。In order to study the permeation behavior of large-tow carbon fiber warp knitted fabrics,the permeability of the carbon fiber preforms with different ply numbers and different stitching structures were measured with unidirectional permeability test method.The experimental results show that:(i)the number of fabric layers directly affects the infusion time of the preform;(ii)the more effective flow channels of the carbon fiber preforms,the higher the permeability;(iii)for fabrics with different stitching structures,preforms made by the same laying method have the highest permeability with the highest number of parallel flow channels of fiber bundles.
