PROCESS OF PRODUCING CERAMIC MATRIX COMPOSITES AND CERAMIC MATRIX COMPOSITES FORMED THEREBY
A process for producing CMC articles that includes reducing the presence of porosity and voids within the articles. The process is performed on a porous fired preform comprising a fiber reinforcement material and a ceramic matrix material, and the preform is densified by heating the preform and a fill material to melt the fill material, and by creating a vacuum that causes the molten fill material to infiltrate and partially fill voids within the preform. While the fill material remains molten within the voids, the preform and fill material are subjected to an increased pressure to further fill the voids with the molten fill material. Thereafter, and while the preform and molten fill material therein remain subject to the increased pressure, the preform and fill material are cooled to solidify the fill material within the voids and yield a CMC article.
