Abstract
Methods of making ceramic matrix prepregs are described. The methods include exposing a coated tow of ceramic fibers to a ceramic matrix slurry comprising a solvent and ceramic precursor. The coating is at least partially removed and the slurry infuses into the ceramic fibers to form prepreg. Steps to form ceramic matrix composites are also described, including forming the prepreg into a green body, and sintering the ceramic precursor.
