R a M a N Spectrum of Modified P a N - B a S E D Carbon Fibers during G R a P H I T I Z a T I O N

چکیده
In the past, we have modified PAN fibers with potassium permanganate, shortened the oxidation time[ 14], enhanced the tensile strength of the carbon fibers[5], and studied the changes in the physical properties and microstructure of fibers during the process of oxidation[6]. in this article, the study is focused on the changes in the microstructure of PAN graphite fibers during the graphitization process. These changes are noted by using wide-angle X-ray diffraction and the Raman spectrum.
