The interface state and mechanical properties of two kinds of domestic T800 carbon fibers were studied.The results showed that compared with class B fibers,the surface roughness of class A fibers was about 23％higher,the O/C content was about 7.4％higher,the active C content was about 20％higher,and the microscopic shear strength was about 10％higher.The compressive strength of Class A fiber reinforced composites after impact is about 8％higher than that of class B fiber.Class A fiber and resin form a better chemical and physical bond,and the interface bond is better.
