CERAMIC MATRIX COMPOSITE BLADE HAVING INTEGRAL PLATFORM STRUCTURES AND METHODS OF FABRICATION
摘要
A method of making a ceramic matrix composite blade includes laying up at least one ply of the plurality of fibrous ceramic plies in a preselected arrangement to form an airfoil and dovetail preform, laying up at least one additional ply of the plurality of fibrous ceramic plies on the airfoil and dovetail preform in a second preselected arrangement to form an integral platform as part of the non-rigidized blade preform, rigidizing the blade preform to form a rigidized blade preform, and densifying the rigidized blade preform to form a ceramic matrix composite blade having an integral platform structure A tool for making the ceramic matrix composite blade and a ceramic matrix composite blade are also disclosed.
