【Abstract】 In this paper, we mainly review recent developments in coal tar pitch for matrix precursor of carbon/carbon composite materials. Several methods of modification of coal tar pitch are described .with focus on carbon yield and rheological properties of modified coal tar pitch at high temperature. The results show further improvement of modified coal tar pitch that is the key to developing carbon/carbon composite materials with low cost and high performance.更多还原
