Abstract
A method for manufacturing a metal bladed wheel of a turbomachine reinforced by an insert made of metal matrix composite material, includes winding the ceramic fibers around a mandrel in order to form the insert, the ceramic fibers being surrounded by a material constituting the matrix; and spark plasma sintering the insert with a powder of metal constituting the bladed wheel to be manufactured.

A method for manufacturing a metal bladed wheel of a turbomachine reinforced by an insert made of metal matrix composite material, said method comprising:
- winding the ceramic fibers around a mandrel in order to form the insert, the ceramic fibers being surrounded by a material constituting the matrix;
- performing a consolidation on the mandrel of the insert by spark plasma sintering with a first powder of metal constituting the bladed wheel to be manufactured;
- placing the consolidated insert in a mold comprising a second powder of metal constituting the bladed wheel to be manufactured, and
- densifying the insert by spark plasma sintering with the second metal powder in the mold.
