采用扫描电子显微镜、X 射线衍射仪、透射电子显微镜、小角X射线散射仪对国产的两种高强中模型碳纤维与日本东丽 T800 H 碳纤维的结构进行表征,比较了它们的表面形貌、断面形貌、石墨微晶结构和微孔结构。结果表明,国产的高强中模型碳纤维的表面形貌优于日本 T800H,但在断面形貌、石墨微晶结构和微孔结构等微观结构上仍有一定差距,需从工艺上进行改进。

The micro-structure of three kinds of high-strength and middle-modulus carbon fiber including two homemade carbon fibers and Toray carbon fibers T800 H were characterized by using scanning electron microscope,X-ray diffrac-tometer,transmission electron microscope and small angle X-ray scattering system.Their surface structure,fracture morphology,graphic micro-crystal structure and micro-pore size were compared.The results indicated that the surface structure of two homemade carbon fibers was better than T800 H.But other micro-structure of the homemade high-strength and middle-modulus carbon fibers had some differences with the Toray carbon fiber.The preparation technolo-gy of the homemade carbon fiber need further improvement.
