PROCESS FOR FABRICATING CARBON-CARBON COMPOSITES
A process for fabricating a carbon-carbon composite article including the steps of: (a) providing a liquid carbon precursor composition; wherein the liquid precursor composition has a neat viscosity of less than about 10,000 mPa-s at 25° C. prior to adding optional components, prior to curing, and prior to carbonizing; and wherein the liquid precursor composition being cured has a carbon yield of at least about 35 weight percent as measured in the absence of optional components; (b) providing a fibrous or a porous carbon material adapted for being infused with the liquid carbon precursor composition of step (a); (c) infusing the fibrous or porous carbon material of step (b), at least one time, with the liquid carbon precursor composition of step (a) to form a liquid carbon precursor-infused preform; (d) heating the liquid carbon precursor-infused preform of step (c) to form a carbon-carbon composite preform; and (e) increasing the density of the carbon-carbon composite preform of step (d) to form a carbon-carbon composite article.
