Abstract
A method for forming a ceramic matrix composite bearing includes preparing a layup slurry from a mixture of water, pre-ceramic polymer and refractory filler. The method further includes forming a concentric stack of slurry-impregnated fabric sleeve layers over a rod-shaped inner mold and applying an outer mold to form a mold assembly. The method also includes heating the mold assembly to form a tubular green body and rough cutting the green body to bearing length. In addition, the method includes heat-treating the bearing and performing a polymer infiltration and pyrolysis treatment. The method further includes conducting dimensional stability treatment processes on the bearing and final grinding and machining to meet pre-determined specifications.
