Bromination was found to increase the oxidation resistance of Thornel P-100 pitch-based carbon fibers in the temperature range from 675 to 925ยฐC whereas it decreased the oxidation resistance of P-X-7 pitch-based carbon fibers. The increased oxidation resistance may be due to bromine adsorption or th

The effects of dispersion of ultrafine a-FeOOH particles of pitch-based activated carbon fibers (ACF) on the adsorption characteristics against NO, SO,, and NH3 were examined at 303 K. Also the micropore structures were studied by Nz adsorption at 77 K. The adsorption isotherms for not only Nz but
Stabilization is an important step for producing pitch-based carbon fiber. In this paper, gas formation rates and weight change during oxidative stabilization, which is most commonly employed as the stabilization method, were measured continuously for three pitch-based yarns, using a mass spectromet
