%X The structural parameters of carbon fiber, pitch-derived carbon and pyrolytic carbon in C/C composites were charaterized by laser Raman microspectroscopy and XRD. In Raman spectra of these carbons, two bands named D and G were observed near 1336.73cm-1 and 1581.00cm-1 respectively, the peak positions do not but the relative intensities of the two bands change with heat treatment temperatures. The relationship between the XRD data of graphitization degree g and R-1 where R is the relative intensity of band D to band G was plotted, the result shows that g increases with the increase of R-1, but the gradient of the R-1-g curve decreases and gradually tends to zero with the increase of R-1, and their relation can be written into the following equation: g = 1- e-2-H(1/R-0.34). The foundation of the correlation between R-1 and g makes it possible to analyze the local distribution of graphitization degree in C/C composites.
