METHOD OF MANUFACTURING A CORE FOR MOULDING A BLADE

摘要

The invention relates to a method of manufacturing a core for moulding a blade of a turbomachine, comprising steps consisting of: - placing a flexible ceramic sheet (1) in a cavity of a mould (2) in such a way as to shape the ceramic sheet (1), - introducing a ceramic paste into the cavity of the mould (2), the ceramic paste forming at least one frame (3) in contact with the ceramic sheet (1), and - co-sintering the ceramic sheet (1) and the frame (3) in such a way as to rigidly join together the ceramic sheet (1) and the frame (3), the frame (3) maintaining the shape of the ceramic sheet (1) given by the mould (2) during the preceding co-sintering phases.
