Abstract
Methods are provided for producing a ceramic matrix composite by slurry infiltration. The methods involve placing a desized ceramic cloth lay-up into a non-ceramic cloth bag, sealing the bag to form a bagged ceramic preform, infiltrating the bagged ceramic preform with a ceramic-containing slurry, and sintering the preform to convert the slurry to a ceramic while decomposing the non-ceramic bag. The methods of the present invention maximize slurry infiltration of the ceramic cloth tow bundle while minimizing damage to the ceramic cloth.
