Meso-structure analysis and permeability prediction of satin fabric based on Micro-CT

  • 摘要: 建立了确定Micro-CT扫描最合适分辨率的方法,并基于CT图像分析了3K五枚缎纹织物的结构,预测了渗透率。首先,将织物理想单胞模型转换为不同分辨率二维切片,考察分辨率对单胞结构、渗透率表征的影响,提出了确定Micro-CT扫描最合适分辨率的方法;其次,采用确定的分辨率对织物进行Micro-CT扫描,获取织物细观结构;最后,使用CT三维细观结构进行厚度方向渗透率数值预测,研究了织物结构的空间离散性对厚度方向渗透率的影响。结果表明:对于本文所用五枚缎纹织物,采用15 μm分辨率进行Micro-CT扫描最为合适;通过Micro-CT可准确获取织物纤维束的路径及截面变化;多层织物的孔隙沿3个主方向均呈现周期性排布,且束间孔隙率均值为16.6%;使用真实CT模型的厚度方向渗透率预测结果与实验值具有良好的吻合性。
