为深入剖析国产HKT800碳纤维的微观结构和性能，用扫描电子显微镜、原子力显微镜、拉曼光谱、X射线衍射仪、压汞仪等对HKT800碳纤维进行了表征，并与东丽T800碳纤维进行了对比分析，结果表明：HKT800碳纤维的表面带有沟槽，少量碳纤维截面呈腰果形，不同于T800碳纤维，且表面粗糙度较大；HKT800碳纤维拉曼测试ID／IG比值为1．07，表面微晶尺寸较小；2种碳纤维层间距均为0．347 nm，孔隙率均为17．4％，比较一致，但HKT800碳纤维堆叠尺寸、取向度略高于T800碳纤维，而微孔偏离碳纤维轴取向程度、微孔长度、微孔横截面平均切割线长度均略低于 T800碳纤维， HKT800碳纤维中微孔尺寸、数量的分布也不同于T800碳纤维．
The microstructure and properties of domestic HKT800 carbon fibers were studied by scanning electron microscopy ( SEM), atomic force microscopy ( AFM), Raman, X?ray diffaction ( XRD) and mercury intrusion porosimetry (MIP). For the purpose of comparison, the microstructure and properties of T800 carbon fibers were also studied. The results showed that numerous grooves distributed on the surface of HKT800 carbon fibers, while few carbon fibers exhibit a cross?section of a cashew?like shape and displayed larger surface roughness, which is different from T800 carbon fibers. The ID/IG value of HKT800 carbon fiber was 1.07, indicating its smaller surface crystalline size. The interlayer spacing and porosity of both HKT800 and T800 carbon fibers, is 3.47 ? and 17.4%, respectively. However, the stack size and orientation degree of HKT800 carbon fibers were slightly higher than those of T800 carbon fibers. The size and number distribution of micropores were also different between HKT800 and T800 carbon fibers, while the HKT800 possessed lower B, L and l than T800.
