通过扫描电子显微镜（SEM ）、原子力显微镜（AFM ）、X射线光电子能谱（XPS）、复丝拉伸法、单丝拉伸法及单丝断裂法对3种国产800‐12K碳纤维表面状态及其复丝拉伸性能、单丝复合体系的界面性能进行系统分析与研究。结果表明：3种国产800级碳纤维表面均较为光滑，纤维的粗糙度为9～17nm ，纤维表面含氧量较高且稳定，O／C在0．23～0．27之间；3种国产800级碳纤维复丝拉伸强度相当，质量控制稳定，断裂伸长率为1．9左右，纤维与树脂基体匹配性较好；3种国产800级碳纤维单丝拉伸强度不稳定，纤维的表面化学活性对纤维与树脂基体的界面结合强度影响显著。
T he surface and micro‐interface property of three domestic 800‐grade carbon fibers (1# , 2# ,3# ) were characterized by Scanning Electron Microscope (SEM ) , Atomic Force Microscope (AFM) ,X‐ray Photoelectron Spectroscopy (XPS) ,multifilament stretching method and single fiber fragmentation test .The results show that the surfaces of these three fibers are all smooth and the roughness is between 9‐17nm .They all possess high content of oxygen ,and the ratio of O/C of the three carbon fibers is between 0 .23‐0 .27 .The multifilament tensile property is similar ,which reveals the domestic carbon fibers have stable quality control ,and the breaking elongation rate of about 1 .9 revealing that the fiber and resin matrix matching is good .The tensile strength of single fiber is unsta‐ble ,meanw hile the high tensile surface active functional group has big influence on the interface shear strength of carbon fibers .
