中文摘要：

建立了平纹织物的细观结构模型，采用均匀化方法预报了其渗透率，与文献中的实验结果比较验证了本文中方法的合理性，同时还对平纹织物纤维预制体细观结构进行了参数研究。对3种平纹玻璃布预制体进行了渗透率测量，与理论预报进行了比较，表明本文中所建立的方法预报的渗透率与实验结果在同一数量级。

英文摘要：

A mesostructures model of the plain weave fabric was set up. The homogenization method was introduced to predict the permeability of the plain fabric preform. The results of the permeability obtained by the approach were compared with the experimental results in the literature, and it shows good agreement. The influence of the mesostruetures parameters on the permeability was discussed. The permeabilities of three kinds of plain glass fabrics were measured and the results were compared with the predicttion. It shows that the permeability obtained by the present method is at the same order of magnitude as the experimental results.
