Preparation of C/C composites with ethanol precursor was studied and the role of ethanol in obtaining high textured (HT) carbon was confirmed. HT carbon was obtained more with ethanol precursor than with propane precursor as reported by Ren et al. The pyrolytic carbon deposition rate constant from ethanol precursor, which has never been reported before in any other research, was obtained. It was confirmed that a proper mixture precursor of ethanol and propane could be used in the process of temperature gradient chemical vapor infiltration (TG-CVI) on behalf of the uniform deposition throughout the preform and the deposition with more HT carbon,. The pyrolytic carbon deposition rate constant for the CVI with propane precursor obtained in this research was 2.2-times greater than that reported by Vaidyaraman.
