Problems solved by technology

[0008] As will be understood by those skilled in the art, not only are low denier fibers expensive and subject to breakage during any of the processing steps described above, but the formation of Ox-Ox components from low denier fabrics involves many time consuming manufacturing steps
Each step further increases the cost of an already expensive low denier fabric

Abstract

An Oxide-Oxide (Ox-Ox) ceramic matrix composite (CMC) component includes a woven high denier ceramic fiber, the fiber comprising a plurality of tows, the woven fiber having interstitial spacing and the tows comprising the fiber having interstitial spacing, an aluminosilicate matrix, wherein the aluminosilicate matrix occupies the interstitial spacing between the fibers, and wherein the aluminosilicate matrix further occupies at least some of the interstitial spacing between the tows of the fiber. In another aspect, a method of fabricating an Oxide-Oxide (Ox-Ox) component includes the steps of providing a ceramic fiber, providing an aluminosilicate slurry, coating the fiber with the aluminosilicate slurry, filament winding the coated fiber over tooling, forming an uncured preform, removing the uncured Ox-Ox preform from the tooling, and curing the Ox-Ox preform, forming a near net shape Ox-Ox component.

Description

[0001] Statement Regarding Federally Funded Research and Development [0002] This invention was made with United States Government support through the Air Force Research Laboratory (AFRL, Air Force Research Laboratory). The United States Government may have certain rights in this invention. technical field [0003] The present invention relates to methods of forming ceramic matrix composite components, and more particularly to methods of forming ceramic matrix composite components having high denier fabric components and related apparatus. Background technique [0004] Currently, ceramic matrix composite (CMC) structures are fabricated by a multi-step process utilizing low denier materials. Denier is a measure of fabric quality in grams per 9000 meters (g / 9000m); generally, lower denier materials are more expensive than higher denier materials. Generally, as used herein, a denier is described with respect to a tow consisting of a plurality of fibers; a higher denier fiber...
