摘　　要：为了了解炭化压力对沥青树脂炭结构的影响程度,在不同的炭化压力下对沥青树脂炭进行了炭化处理,并采用XRD、SEM等方法对处理后的沥青树脂炭的结构进行了分析。试验结果显示,随着炭化压力的提高,沥青树脂炭开孔率降低,残炭率提高,微观结构取向性增强,在本次试验中,炭化压力的不同,对沥青树脂炭的石墨化性能影响较小。In order to research the influence of carbonization pressure on the structure of Condensed Polynuclear Resin carbons, Condensed Polynuclear Resin carbons were treated at different pressure, and the structure of Condensed Polynuclear Resin carbons were tested by XRD, SEM. The results indicated that porosity of Condensed Polynuclear Resin carbons decrease, the ratio of remnant carbon increase, orientation of microstructure strengthen, while crystal structure of Condensed Polynuclear Resin carbons under different carbonization pressure is close in this experiment.
