| Abstract: | 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. |
