Abstract: According to the character of the X-ray diffraction patterns of different phases in PAN carbon fiber, it can be affirmed that there still exist plentiful monolayer graphite with six-membered ring, besides multilayer graphite. We also found two kinds of quantative methods for analyzing crystaline phase with defaults, which can be used to study the effect of monolayer graphite in carbon fiber upon its mechanical property.
