cost effective manufacturing process for high performance composites keramikmatrix

摘要

A method for manufacturing a ceramic matrix composite article. The method includes providing a plurality of ceramic fiber tows [10]. The method further includes depositing a coating comprising a layer of boron nitride [20], a layer of silicon-doped boron nitride [30], a layer of silicon nitride [40], and a layer of carbon [50]. The method further includes assembling the coated fiber tows into a plurality of plies of ceramic cloth. The method further includes laying up the plies of ceramic cloth into an article form. The method further includes densifying the article form using a material selected from the group consisting of ceramic particulates, ceramic precursor resins, and combinations thereof and using a method selected from the group consisting of slurry casting, resin transfer molding, vacuum impregnation, and combinations thereof. The method further includes infiltrating the article form with at least silicon to form a ceramic matrix composite article with a substantially continuous matrix.
