Title:
METHOD FOR MAKING GAS TURBINE ENGINE COMPOSITE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2014/163703
Kind Code:
A3
Abstract:
A method for making a gas turbine engine matrix composite structure. The method includes providing at least one metal core element, fabricating a matrix composite component about the metal core element, and removing at least part of the metal core element from the matrix composite component by introduction of a halogen gas. SiC/SiC, C/C/SiC, C/SiC or oxide/oxide CMC's are made. The structure is used for gas turbine blades. A carbon release on the metal core is converted to SiC.
