| Abstract: | The samples of PAN - based carbon fiber with different carbonization temperatures are measured by small angle X- ray scattering technique. Based on SAXS theory and fractal theory, we obtain the calculating method and calculating formulas of the pore size, pore volume percentage and the fractal of pore surface in PAN- based carbon fiber. Computing program is used in analyzing SAXS data. The changing of those parameters according carbonization temperature and their effects to mechanical properties of PAN - based carbon fiber has been given. |
