Abstract

A ceramic matrix composite article and a process of fabricating a ceramic matrix composite are disclosed. The ceramic matrix composite article includes a matrix distribution pattern formed by a manifold and ceramic matrix composite plies laid up on the matrix distribution pattern, includes the manifold, or a combination thereof. The manifold includes one or more matrix distribution channels operably connected to a delivery interface, the delivery interface configured for providing matrix material to one or more of the ceramic matrix composite plies. The process includes providing the manifold, forming the matrix distribution pattern by transporting the matrix material through the manifold, and contacting the ceramic matrix composite plies with the matrix material.

First claim

What is claimed is:

1. A ceramic matrix composite article, comprising:
a matrix distribution pattern formed by a manifold; and
ceramic matrix composite plies laid up on the matrix distribution pattern;
wherein the manifold includes one or more matrix distribution channels operably connected to a delivery interface, the delivery interface configured for providing matrix material to one or more of the ceramic matrix composite plies;
wherein the article is a turbine component.

2. The article of claim 1 , wherein the manifold is a consumable insert.

3. The article of claim 1 , wherein the matrix distribution pattern is devoid of micro-porosity.

4. The article of claim 1 , wherein the manifold includes chopped fibers in a material defining the one or more matrix distribution channels.

5. The article of claim 1 , wherein the manifold includes a plurality of sub-manifolds.

6. The article of claim 5 , wherein the plurality of sub-manifolds includes a first sub-manifold and a second sub-manifold.

7. The article of claim 1 , wherein the turbine component is selected from the group consisting of a wide component, a shroud, a nozzle, a combustion liner, a turbine case, a shroud ring, a turbine strut, an exhaust duct, an augmentation liner, a jet exhaust nozzle, an exhaust nozzle flap, a vectoring nozzle component, and combinations thereof.

8. The article of claim 7 , wherein the turbine component is a shroud.

9. The article of claim 1 , wherein the one or more matrix distribution channels are substantially parallel.

10. The article of claim 1 , wherein the one or more matrix distribution channels slightly converge.

11. The article of claim 1 , wherein the one or more matrix distribution channels are arranged in a substantially orthogonal grid.

12. The article of claim 1 , wherein the delivery interface includes apertures positioned to deliver the matrix material to the one or more of the ceramic matrix composite plies.

13. The article of claim 1 , wherein the manifold further comprises an outer layer positioned between the delivery interface and the one or more of the ceramic matrix composite plies.

14. The article of claim 1 , wherein the turbine component is selected from the group consisting of a portion of a dovetail of a blade, a flange, an airfoil, a platform, and combinations thereof.

15. A ceramic matrix composite article comprising:
a manifold; and
ceramic matrix composite plies laid up on the manifold;
wherein the manifold includes one or more matrix distribution channels operably connected to a delivery interface, the delivery interface configured for providing matrix material to one or more of the ceramic matrix composite plies and wherein the article is a turbine component.

16. The article of claim 15 , wherein the manifold includes a plurality of sub-manifolds.

17. The article of claim 15 , wherein the turbine component is selected from the group consisting of a wide component, a shroud, a nozzle, a combustion liner, a turbine case, a shroud ring, a turbine strut, an exhaust duct, an augmentation liner, a jet exhaust nozzle, an exhaust nozzle flap, a vectoring nozzle component, and combinations thereof.

18. The article of claim 17 , wherein the turbine component is a shroud.

19. The article of claim 15 , wherein the turbine component is selected from the group consisting of a portion of a dovetail of a blade, a flange, an airfoil, a platform, and combinations thereof.

20. A process of fabricating a ceramic matrix composite article, comprising: forming a matrix distribution pattern by transporting a matrix material through a manifold, the manifold including one or more matrix distribution channels operably connected to a delivery interface, the delivery interface configured for providing matrix material to one or more ceramic matrix composite plies; and contacting the one or more of the ceramic matrix composite plies with the matrix material, wherein the article is a turbine component.

21. The process of claim 20 , wherein the manifold includes a plurality of sub-manifolds.

22. The process of claim 20 , including fabricating as the turbine component an article selected from the group consisting of a wide component, a shroud, a nozzle, a combustion liner, a turbine case, a shroud ring, a turbine strut, an exhaust duct, an augmentation liner, a jet exhaust nozzle, an exhaust nozzle flap, a vectoring nozzle component, and combinations thereof.

23. The process of claim 22 , including fabricating the shroud as the turbine component.

24. The process of claim 20 , including fabricating as the turbine component an article selected from the group consisting of a portion of a dovetail of a blade, a flange, an airfoil, a platform, and combinations thereof.
