Beschreibung
Zusammenfassung:	The present invention is ceramic matrix composite gas turbine engine component comprising a plurality of cured ceramic matrix composite plies 44, each ply 44 comprising ceramic fiber tows 46, each ceramic fiber tow 46 comprising a plurality of ceramic fibers 72, the tows 46 in each ply 44 lying adjacent to one another such that each ply has a unidirectional orientation. The component further comprises a layer of a coating 48 on the ceramic fibers. The component further comprises a ceramic matrix material 64 lying in interstitial regions between the fibers 72 and tows 46 of each ply 44 and the interstitial region between the plurality of plies 44, wherein at least a portion of the component is no greater than about 0.021 inch thick. The present invention is also a method for making such a ceramic matrix composite component.
