TLDR
In this article, a gas turbine engine is formed from a continuous fiber reinforced ceramic matrix composite (CMC), which has a sealing portion which makes sealing contact with an adjacent component of the engine.Abstract:
A component (31) of a gas turbine engine is formed from a continuous fibre reinforced ceramic matrix composite (CMC). The component has a sealing portion which, in use, makes sealing contact with an adjacent component of the engine. The sealing portion comprises a recess (35) formed in the CMC and filled with a finer grade ceramic (36) relative to the surrounding CMC, a metal or an intermetallic.read more

Cmc shroud support system of a gas turbine
TL;DR: In this paper, a retainer support system with load spreading is described, where the retainer passes through the shroud, passing through the first and second bolt holes, engaging the second and third bolt holes.
Patent
CMC shroud support system
TL;DR: A shroud and shroud hanger are provided in this article, where at least the shroud is formed of ceramic matrix composite material and the shroud and hanger extend in a circumferential direction and a generally C-shaped clip extends radially to retain the hanger and shroud together.
Patent
Seals for gas turbine engines
TL;DR: In this paper, a turbine shroud for use in a gas turbine engine that includes a metallic carrier, a blade track, and a seal is disclosed, and the seal is engaged with surfaces of the metallic carrier and the blade track to block ingress of hot gasses at the interface of the blade tracks and the metallic carriers.
