摘　　要：根据聚丙烯腈基碳纤维微孔表面的特点,计算了碳纤维微孔缺陷表面的分形维数,并分析了分形维数与拓扑维数之差的关系。结果表明:碳纤维内部微孔表面的分形维数在热处理温度升高的同时表现为增大,说明微孔表面粗糙度增大。从统计意义上讲,显露于微孔缺陷表面的分形结构自相似性更显著。The fractal dimension of microporous surface was calculated according to the characteristics of？ microporous surface in polyacrylonitrile carbon fiber. The difference between fractal dimension the topological dimension was analyzed. The results show that with heat treatment temperature increasing, fractal dimension increases, reflecting the micropore surface roughness increases. In statistical sense, self - similarity appeared in fraetal dimension of microporous defects becomes more apparent.
