Microstructures and surface chemical and physical characters of M40J and T300 carbon fibers were investigated by scanning electron microscopy, transmission electron microscope, X-ray photoelectron spectroscopy, X-ray Diffraction, Raman spectroscopy and elemental analysis. Results show that M40J fiber has a higher carbon content, less nitrogen and less surface active component in comparison with T300 fiber. The surface of M40J and T300 carbon fibers has many grooves, longer and shallower for M40J, shorter and deeper for T300. T300 carbon fiber shows an obvious sheath-core structure,while M40J shows homogeneous structures. The erystallite structure and orientation of M40J carbon fiber is better in comparison with T300 carbon fibers.
