发明名称 Method for making ceramic matrix composite articles
摘要 A method of forming a composite article includes impregnating an inorganic fiber preform with a slurry composition. The slurry composition includes a particulate, a solvent, and a pre-gellant material. Gelling of the pre-gellant material in the slurry composition is initiated to immobilize the particulate and yield a gelled article, and substantially all solvent is removed from the gelled article to form a green composite article. The green composite article is then infiltrated with a molten infiltrant to form the composite article.

主权项 1. A method of forming a composite article, the method comprising: impregnating an inorganic fiber preform with a slurry composition, wherein the slurry composition comprises a particulate, a solvent, and a pre-gellant material; initiating gelation of the pre-gellant material in the slurry composition to immobilize the particulate and yield a gelled article; removing substantially all solvent from the gelled article to form a green composite; and infiltrating the green composite article with a molten infiltrant to form the composite article.
