Abstract
Official abstract text for this publication.
A method of making a ceramic matrix composite (CMC) brake component may include the steps of applying a pressure to a mixture comprising ceramic powder and chopped fibers, pulsing an electrical discharge across the mixture to generate a pulsed plasma between particles of the ceramic powder, increasing a temperature applied to the mixture using direct heating to generate the CMC brake component, and reducing the temperature and the pressure applied to the CMC brake component. The ceramic powder may have a micrometer powder size or a nanometer powder size, and the chopped fibers may have an interphase coating.
First claim
Opening claim text (preview).
What is claimed is: 1. A ceramic matrix composite (CMC) brake component for an aircraft, comprising: an annular disc comprising: a ceramic material having a monolithic grain structure, wherein the ceramic material comprises at least one of SiC, B 4 C, or Si 3 N 4 ; and chopped fibers disposed within the ceramic material, wherein the chopped fibers are coated with an interphase layer, wherein the chopped fibers comprise at least one of carbon fibers or SiC fibers, wherein the interphase layer is configured to inhibit fiber sintering to the ceramic material, and wherein the monolithic grain structure has controlled proportions of ceramic material to chopped fibers resulting in a first upper use temperature, the first upper use temperature being greater than a second upper use temperature of a melt infiltration (MI) composite.
