A 23 factorial statistically designed experiment was used to study fabrication of carbon/carbon composites using the forced flow-thermal gradient chemical vapor infiltration process. Propane, diluted with hydrogen, was used as the feed. The independent variables were the temperature of the bottom of
Carbon/carbon composites with porosities as low as 7% were fabricated within 8-12 hours using the forced flow-thermal gradient chemical vapor infiltration (FCVI) process. Preforms consisting of 40 layers of T-300 plain weave carbon cloth were infiltrated with a feed containing a carbon source and a
