Abstract
An article of manufacture includes a first ceramic matrix composite (CMC) sheet having a number of flow passages therethrough, and a CMC foam layer bonded to the first CMC sheet. The CMC foam layer is an open-cell foam. The article of manufacture includes a second CMC sheet bonded to the CMC foam layer, the second CMC sheet having a thermal and environmental barrier coating and having a number of flow passages therethrough.
Claims19
A method, comprising:
- forming a first ceramic matrix composite (CMC) sheet, and providing a plurality of flow paths therethrough;
- rigidizing the first CMC sheet into a component shape;
- bonding a shaped, open-cell CMC foam layer to the first CMC sheet;
- forming a second CMC sheet;
- bonding the second CMC sheet to the foam layer thereby forming a component structure;
- and
- curing the component structure.

A method, comprising:
- providing a multi-layer ceramic matrix composite (CMC) component comprising two opposing CMC sheets and a CMC open-cell foam layer therebetween;
- exposing one of the CMC sheets directly to high-temperature turbine engine gases;
- and
- flowing a coolant fluid through the CMC open-cell foam layer and through a plurality of flow passages defined by at least one of the CMC sheets.
