Method of Forming a Ceramic Matrix Composite and a Ceramic Matrix Composite Component

摘要

A method of forming a ceramic matrix composite component includes providing a formed ceramic member (90) having a cavity (70), filling at least a portion of the cavity (70) with a ceramic foam. The ceramic foam is deposited on a barrier layer (40) covering at least one internal passage (50) of the cavity (70). The method (600) includes processing the formed ceramic member (90) 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.
