The results show that the microscopical pore structure of the three dimensional orthogonal woven carbon fabric structure perform is composed of body-centered cubes which arranged periodically at spaces. The net structure and shape of the pores of perform are determined by the size and proration of the fasciculus diameter, which are key factors influencing the gaseous permeability and final density of composites. Once the proration of the fasciculus diameters of different directions is determined, the trend of diversification of the permeability followed by pore rate during CVI process and the density of composites are stated, and the permeability increases with the increase of the fasciculus diameter.

研究结果表明：三维正交结构炭纤维预制体的宏观孔隙结构在空间上可以看成是由呈周期性排列的体心立方&晶胞&构成； X ， Y 和 Z 3个方向纤维束直径大小及比例关系决定三维正交结构炭纤维预制体宏观孔隙网络的结构和形状，也是决定反应气体在孔隙中的比渗透率和复合材料最终致密度的重要因素；当 X ， Y 和 Z 3个方向纤维束直径的比例关系一定时，不同预制体在CVI增密过程中比渗透率随孔隙率变化的趋势相同；复合材料的最终致密度一定；比渗透率随纤维束直径增大而略有增大。
