Rotating airfoil fabrication utilizing Ceramic Matrix Composites

Disclosed is an airfoil (26) comprising a plurality of ceramic matrix composite (CMC) fabric sheets (37) which are layered to form a single, layered fabric sheet. The layered fabric sheet is formed so as to define a pressure and suction side (38,42) of the airfoil. The airfoil includes primary fiber...

Beschreibung
Zusammenfassung:	Disclosed is an airfoil (26) comprising a plurality of ceramic matrix composite (CMC) fabric sheets (37) which are layered to form a single, layered fabric sheet. The layered fabric sheet is formed so as to define a pressure and suction side (38,42) of the airfoil. The airfoil includes primary fibers (48) which extend radially outwardly from a rotor disk (25), for example. In this way, the airfoil is suitable for use in a gas turbine engine (10) due to the temperature resistance of CMC and the strength provided by the primary fibers.
