doi:10.19936/j.cnki.2096-8000.20210328.015

Abstract

Abstract: The carbon fiber yields of different diameter PAN fibers under different pre-oxidation conditions were analyzed, and the effect of PAN fiber diameter on carbon fiber yield was discussed by TG, XPS, NMR, Raman. The results showed that the higher the pre-oxidation temperature, the higher the carbon fiber yield. The carbon fiber yields of thick-diameter PAN fibers were higher than that of thin-diameter fibers under the same process conditions. The TG of the thick-diameter PAN fibers had been lower than that of the thin-diameter fibers. Under the same condition, the pre-oxidation degree of thin-diameter PAN fibers was higher than that of thick-diameter PAN fibers. However, the surface elements of different diameter of pre-oxidation fibers and the microcrystalline structure of carbon fibers surface had no difference.

Key words: PAN fiber, diameter, pre-oxidation, carbonization, yield, composites
