Appl. No.:

11/229346

Inventors:

Carlos Bacalski - San Diego CA, US

International Classification:

B28B 3/00
B32B 19/00
B28B 1/00

US Classification:

428688000, 264642000

Abstract:

A method of forming a structurally integrated component. The method comprises providing a first ceramic material comprising an oxidation sensitive ceramic material and providing a second ceramic material comprising an uncured, oxide ceramic matrix composite. The first ceramic material may be a carbon-based ceramic material selected from the group consisting of carbon fibers, carbon whiskers, carbon powder, graphite, silicon carbide, silicon oxycarbide, and mixtures thereof. The second ceramic material may comprise an inorganic oxide fiber reinforcement impregnated with an alumina matrix or an aluminosilicate matrix. The second ceramic material and the first ceramic material are contacted to form an uncured, structurally integrated precursor component, which is co-cured. The co-cured, structurally integrated precursor component is then co-fired in an inert atmosphere to bond the first ceramic material and the second ceramic material. A co-cured, structurally integrated precursor component and a structurally integrated component are also disclosed.

Abstract:

The need for a woven screen or mesh is eliminated in composite acoustic liners by providing an absorptive acoustic liner in which the perforated facesheet has a coating of an erosion-resistant material applied thereto. The coating can be applied using a simple spraying process. The acoustic liner can be easily tuned by regulating the thickness of the coating.
