20130210299 | REINFORCED COATINGS AND METHODS OF MAKING THE SAME - A reinforced coating for a substrate includes a bond coat layer bonded to a surface of the substrate; an intermediate layer bonded to the bond coat layer; a reinforced layer bonded to the intermediate layer, wherein the reinforced layer comprises a woven fiber mesh disposed in the reinforced layer in a substantially planar position. | 08-15-2013 |
20140048978 | CONSUMABLE CORE FOR MANUFACTURE OF COMPOSITE ARTICLES AND RELATED METHOD - Systems, methods and devices adapted to ease manufacture of composite articles (e.g., ceramic composite articles), particularly composite articles which include a hollow feature are disclosed. In one embodiment, a system includes: a consumable core formed to be disposed within an inner portion of a composite precursor, the consumable core adapted to convert into an infiltrant during a manufacturing process and infiltrate the composite precursor. | 02-20-2014 |
20140271208 | SYSTEMS AND METHOD FOR A COMPOSITE BLADE WITH FILLET TRANSITION - A system includes a turbomachine blade segment including an airfoil with an exterior surface, and a platform coupled to the airfoil having a first side and a second side. The system also includes a concave fillet transition extending between the airfoil and the platform. The concave fillet transition includes one or more interface ply segments extending across the exterior surface of the airfoil and the first or the second side of the platform to form a continuous surface between the airfoil and the platform. | 09-18-2014 |
20150147184 | PROCESS OF PRODUCING A CERAMIC MATRIX COMPOSITE TURBINE BUCKET, INSERT FOR A CERAMIC MATRIX COMPOSITE TURBINE BUCKET AND CERAMIC MATRIX COMPOSITE TURBINE BUCKET - A process of producing a ceramic matrix composite turbine bucket, an insert for a ceramic matrix composite turbine bucket, and a ceramic matrix composite turbine bucket are disclosed. The process includes providing a bucket preform having a dovetail cavity, the dovetail cavity being enclosed within a dovetail shank of the bucket preform, positioning an insert within the dovetail cavity, then forming the ceramic matrix composite turbine bucket in a furnace. The insert includes a geometry configured to be fit within a dovetail cavity of the ceramic matrix composite turbine bucket, a bucket preform, or both. The insert is foam material or a plurality of ceramic matrix composite plies. The ceramic matrix composite turbine bucket includes a dovetail shank and a dovetail cavity enclosed within the dovetail shank. The dovetail cavity is arranged and disposed for receiving an insert. | 05-28-2015 |
20150369052 | Thin-Walled Reinforcement Lattice Structure for Hollow CMC Buckets - A hollow ceramic matrix composite (CMC) turbine bucket with an internal reinforcement lattice structure has improved vibration properties and stiffness. The lattice structure is formed of thin-walled plies made of CMC. The wall structures are arranged and located according to high stress areas within the hollow bucket. After the melt infiltration process, the mandrels melt away, leaving the wall structure to become the internal lattice reinforcement structure of the bucket. | 12-24-2015 |
20150377074 | DEBRIS REMOVAL SYSTEM - A casing for a turbo-machine at least partially defines a flow path for a working fluid through or around one or more of a compressor section, a combustor assembly, or a turbine section. The casing defines an inner surface and the inner surface defines a plurality of debris routing channels. The plurality of debris routing channels are configured to route debris in a working fluid within the casing towards a debris collection mechanism. | 12-31-2015 |
