FILAMENT WOUND HIGH DENIER ALUMINUM OXIDE FIBER COMPONENTS AND METHODS OF MAKING

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.
