| Abstract: | PAN/PPG precursors were pre-oxidized and carbonized,the influences of PPG on the structures and properties of the pre-oxidized and carbonized PAN fibers were studied by SEM,FTIR,elemental analysis and me-chanical testing.The results indicated that,with the introduction of PPG,the pre-oxidized fiber surfaces became more homogeneous and the carbon fibers interior holes decreased;The addition of PPG also enhanced the oxida-tion reactions during pre-oxidation and carbonation processes,and the mechanical propert... |
