Abstract
A method of preparing a ceramic fabric for use in a ceramic matrix composite includes arranging a plurality of tows to form a ceramic fabric with a first inter-tow spacing, applying a binder material to the ceramic fabric, and applying pressure to the ceramic fabric to form a pressure stabilized ceramic fabric. Each of the plurality of tows of the ceramic fabric has a first thickness, and each of at least a subset of the plurality of tows of the pressure stabilized ceramic fabric has a second thickness less than the first thickness.
