| 摘 要： | 分别对两种不同组成的沥青及对苯二甲醛改性后的沥青的流变、浸渍性能及最终C/C复合材料的光学结构进行了研究.结果表明:沥青的流变性能越好、喹啉不溶物(QI)含量越低,其浸渍性能越好,并且其光学各向异性组织单元尺寸越大;与未改性沥青比较,改性沥青前两次浸渍-碳化循环的效率较高,其C/C复合材料的致密化效果显著.

| Abstract: | Rheological properties and the impregnating performance of three pitches,including terephthalic aldehyde-modified pitch,and optical textures of resultant carbon-carbon composites,were studied.The results showed that the impregnating performance of pitch became good,and anisotropic unit size of the optical textures got large with improvement of rheological properties and decrease of quinoline insoluble(QI) content.Moreover,the impregnating efficiency of the modified pitch,indicated by densification degree of carbon-carbon composites,was much higher than those of the unmodified pitches during first two impregnation/carbonization cycles. |
