以廉价的国产中温煤沥青为原料,通过特定的交联催化反应,合成了一种适合于炭/炭复合材料用的基体——COTAP,并研究了不同反应条件下COTAP基体的残炭率及其与炭纤维之间的润湿性,以及由其制备的炭/炭复合材料的强度。实验结果表明,COTAP基体具有良好的综合性能,是一种很有价值的炭/炭复合材料用基体。 A kind of suitable medium for carbon / carbon composites, COTAP, was prepared by using cheap domestic coal tar pitch as raw material through a specific cross-linking catalysis reaction. The carbon residue rate of COTAP matrix under different reaction conditions and Its wettability with carbon fibers, and the strength of the carbon / carbon composite prepared therefrom. The experimental results show that, COTAP matrix has good overall performance, is a very valuable carbon / carbon composite matrix.
