Hybrid ceramic matrix composite turbine vane assembly |
| abstract |
A hybrid turbine blade 10 includes a composite core 16 enclosed within a composite shell 14. The composite core includes a mixture of silicon carbide, silicon and carbon; the composite shell includes a wound or woven ceramic silicon carbide fiber material. A method of forming the blade may include the steps of (a) shaping a carbon preform; (b) reacting the preform in a furnace with silicon at a temperature above the melting point of silicon to form a CMC composite core component 16 made up of a mixture of silicon carbide, silicon and carbon; (c) locating a temporary mandrel core component 18 adjacent the CMC composite core component 16 to form a multi-core assembly; (d) forming a composite shell 14 by laying up prepreg tapes around the multi-core assembly; and (e) removing the temporary mandrel core 18. The shell 14 may then be subjected to melt infiltration of molten silicon. Alternatively, the shell and the core may be melt-infiltrated simultaneously. |
