Abstract
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.

A method of forming a ceramic matrix composite component comprising:
- providing a formed ceramic member having a cavity;
- filling at least a portion of the cavity with a ceramic foam;
- and
- processing the formed ceramic member and ceramic foam to obtain a ceramic matrix composite component.
A method of forming a ceramic matrix composite blade comprising:
- providing a partially cured ceramic matrix composite blade shell, wherein the ceramic matrix composite blade shell has a cavity and the ceramic matrix composite blade shell has at least one internal passage;
- applying a barrier layer adjacent to the at least one internal passage in the cavity of the ceramic matrix composite blade shell;
- filling at least a portion of the cavity with a ceramic foam, the ceramic foam being applied to the barrier layer and operable to form a tip member;
- and
- processing the partially cured ceramic matrix composite blade shell and the tip member to form a ceramic matrix composite blade.
A ceramic matrix composite component comprising:
- a formed ceramic member having a cavity;
- a barrier layer applied to the cavity of the formed member;
- and
- a ceramic foam applied to the barrier layer and filling the cavity, wherein the formed ceramic member including the ceramic foam is processed to form a ceramic matrix composite component.
