Abstract
A method for producing ceramics reinforced with three-dimensional fibers, which entails: a) setting a filter plate in contact with one surface of a three-dimensional fiber preform and a porous metallic plate in contact with said filter plate; b) setting a slurry in contact with a surface of the preform opposite to the one surface; c) exerting pressure on the slurry and, at the same time, subjecting the preform to vacuum aspiration through the filter plate, thereby obtaining a composite having an impregnated preform, the impregnation being effected in a single step; d) heating the composite; and e) firing the resultant composite.
