In this study, the method of preparing the transversal and longitudinal sections of carbon fiber used for Raman scattering spectrum measurement was proposed. Raman mapping was performed on the transversal and longitudinal sections of three T800 carbon fibers, domestic JHT55, P278F and Toray T800S. By comparing the graphitization degrees(GD), the homogeneity distributions of the samples in radial and axial directions and along the equator were discussed. The result showed that three T800 carbon fibers all have skin-core structures, but their homogeneities are different. The Toray T800S carbon fiber has the highest homogeneity, which indicates an important factor that leads to a better performance than the domestic ones in their application fields.
