Abstract
A method of producing a densified carbon fiber reinforced carbon (carbon/carbon) component includes placing a carbon/carbon preform and preform heater(s) into a reactor vessel with an immersing quantity of a precursor liquid (e.g., hydrocarbon). The reactor vessel includes a condenser for condensing precursor gases (e.g., carbonaceous gases) produced during densification and thereby maintain a thermodynamic equilibrium. Electrical current is supplied to the preform heater over a multi-hour period of densification in which the precursor liquid is continually boiled and the precursor gases continually produced. The current is sufficient to maintain the preform at a densification temperature above a precursor cracking temperature, thereby causing the precursor gases to be diffused into the preform and dissociated gas species to be deposited. Densification begins within the preform and advances outwardly along a densification front until completion.
