Abstract

In the method for making a ceramic matrix composite article comprising the steps of providing a porous preform for the article formed of a combination of a fibrous reinforcing material and a ceramic matrix material, and thereafter consolidating the preform by the application of heat and consolidation pressure thereto, improved consolidation of preforms of curved or other complex configuration is achieved by applying consolidation pressure to the preforms through the medium of a softened glass.
