Method beneficial to densification of internal mass of ceramic matrix composite material
The invention discloses a method for facilitating internal mass densification of a ceramic matrix composite. According to the method, during weaving of a fiber preform, the fiber preform is woven in the following weaving mode that at least two strands of warp are arranged on the surface and outer layers in the warp direction, one strand of warp is arranged on the inner layer in the warp direction, and one strand of weft is arranged on each of the surface and outer layers and the inner layer in the weft direction. The outer layer gap of the prefabricated body is large, the inner layer gap is small, and the matrix filling rate problem and the internal gap forming problem are perfectly solved.
本发明公开了一种利于陶瓷基复合材料内部质量致密化的方法，该方法在纤维预制体的编织中采用以下编织方式编织而成：表外层经向至少为2股经线，内层经向为1股经线，表外层、内层纬向均为1股纬线。本发明形成的预制体外层间隙较大，内层间隙较小，完美解决基体填充速率问题和内部空隙形成问题。
