CERAMIC MATRIX COMPOSITE

摘要

The invention concerns an article (20) formed of a ceramic matrix composite structure having a plurality of ceramic fibre layers (22) and a binder material (24) interspersed throughout said layers. The ceramic matrix composite material may be sintered. The ceramic fibre layers undulate relative to one or more outer surfaces (38;40) of the article. Thus support features (48) within the article are able to share a load in use between a plurality of layers. The invention may be suited to engine components such as turbine seal segments in a gas turbine engine.
