Method of producing an internal cavity in a ceramic matrix composite and mandrel therefor

Title: Method of producing an internal cavity in a ceramic matrix composite and mandrel therefor

Abstract

A process for producing an internal cavity in a CMC article and mandrels used therewith. The process entails incorporating a mandrel made of a material that is substantially absorbed during thermal treatment of a preform to form the CMC article. The mandrel material is preferably reactive with one or more constituents of the CMC preform during the thermal treatment. The material is preferably silicon or a silicon alloy.

Method of producing an internal cavity in a ceramic matrix composite

Patent Gray, Paul Edward; Roberts, III, Herbert Chidsey; Taxacher, Glenn Curtis; ...

A process for producing an internal cavity in a CMC article and mandrels used therewith. The process entails incorporating a mandrel made of a fusible material that is melted and drained during a thermal treatment of a CMC preform to form the CMC article. The mandrel material is preferably non-wetting and non-reactive with any constituents of the CMC preform during the thermal treatment. The mandrel is preferably tin or an alloy of tin.

Method of forming a ceramic matrix composite and a ceramic matrix component

Patent de Diego, Peter; Zhang, James

A method of forming a ceramic matrix composite component includes providing a formed ceramic member having a cavity, filling at least a portion of the cavity with a ceramic foam. The ceramic foam is deposited on a barrier layer covering at least one internal passage of the cavity. The method includes processing the formed ceramic member and ceramic foam to obtain a ceramic matrix composite component. Also provided is a method of forming a ceramic matrix composite blade and a ceramic matrix composite component.

Process of producing a ceramic matrix composite article and article formed thereby

Patent Corman, Gregory Scot [Ballston Lake, NY]; McGuigan, Henry Charles [Duanesburg, NY]; Brun, Milivoj Konstantin [Ballston Lake, NY]

A CMC article and process for producing the article to have a layer on its surface that protects a reinforcement material within the article from damage. The method entails providing a body containing a ceramic reinforcement material in a matrix material that contains a precursor of a ceramic matrix material. A fraction of the reinforcement material is present and possibly exposed at a surface of the body. The body surface is then provided with a surface layer formed of a slurry containing a particulate material but lacking the reinforcement material of the body. The body and surface layer are heatedmore »« less
