| 摘 要： | 对C／C复合材料的烧蚀表面粗糙度进行了测量，并对不同编织结构和不同基体组元的C／C复合材料的烧蚀表面粗糙度进行了比较分析。研究发现：基体组元相同时采用多向结构的C／C复合材料烧蚀表面粗糙度明显降低；编织结构相同时，舍有沉积碳组元的碳／碳复合材料烧蚀表面粗糙度明显降低。

| Abstract: | Ablated Surface roughness of C/C composites is measured and ablated surface roughness of C/C composites with different carbon matrices and structures is analyzed. It is found that the ablated surface roughness of multi-directional C/C composites is obviously lower than that of 3D C/C composites with same carbon matrix. On the other hand , the ablated surface roughness of C/C composites with a pyrolytical carbon matrix is obviously lower than that of C/C composites with a pitch-derived carbon matrix when the same braiding structure is used for composites. |
