摘要
系统地介绍了近年来 C/C 复合材料基体用沥青的改性方法。为获得较好的浸渍性能,在提高沥青残炭率的同时,应兼顾其流动性、粘度和软化点等因素,以减少浸渍次数,降低 C/C 复合材料的成本。
This paper mainly introduces the several methods of modification of coal tar pitch for matrix precursor of carbon/carbon composite materials in recent years. In order to obtain the preferable impregnation performance and reduce the cost of C/C composite, much attention should be given to the factors of fluidity, viscidity, soft point etc.
