Summary

The forced flow-thermal gradient chemical vapor infiltration (FCVI) process was used to fabricate carbon fiber-carbon matrix composites. Cloth layup preforms were infiltrated using propylene, propane, or methane, with hydrogen as a diluent. Composites of 0.8 cm thickness with total porosities as low as 7% were prepared in 8 h. The highest deposition rate obtained in the present study was ∼3 pm/h which is more than an order of magnitude faster than the typical value of 0.1-0.25 um/h for the isothermal infiltration process. The results show that the FCVI process is readily applied to the rapid fabrication of carbon-carbon.
