Abstract
The correlation between the redox behavior of surface compounds formed in dilute sulfuric acid and the heat treatment temperature (HTT) of 2 D-C/C composites whose fibers are made of PAN was investigated by using X-ray diffraction analysis (XRD) and cyclic voltammetry (CV). XRD results indicate that the reflection intensity increased with HTT but that the half-value width decreased. These results suggest that the graphite structure developed with increasing HTT. Cyclic voltammograms were measured for both x-y planes parallel to woven laminates and x-z planes perpendicular to these. For both planes, the current corresponding to the formation of phenol-type compounds (at 0.3V-0.4V) was suppressed with increasing HTT, i.e, the graphite structure development. The anodic currents between 0.3V and 0.4V for the x-z plane at the same HTT was lower than those for the x-y plane. The current corresponding to the formation of carbonyl compounds (at 0.8V), in contrast increased with HTT. The reduction current observed from 1.0V increased with decreasing HTT.
