Carbon fibers are prepared by stabilizing pitch fibers accompanying electron beam (E-beam)irradiation. The carbon fibers pretreated by E-beam irradiation achieve a higher stabilizationindex than the carbon fibers that are only heat-stabilized. In addition, the carbon fiberssubjected to E-beam irradiation in the stabilization step exhibit a comparable tensile strengthto that of general purpose carbon fibers. The carbon fibers pretreated with an absorbed doseof 3000 kGy have a tensile strength of 0.54 GPa for a similar fiber diameter. Elemental,Fourier-transform infrared spectroscopy, and thermogravimetric analyses indicate that Ebeamirradiation is an efficient oxidation and dehydrogenation treatment for pitch fibers byshowing that the intensity of the aliphatic C?H stretching and aromatic CH2 ben영어 초록
