Abstract
A method for manufacturing a turbomachine blade made of ceramic matrix composite component includes at least a structural part and a functional part secured to the structural part, the method including obtaining an assembly including a first preform of the functional part that is mounted on a second preform of the structural part or on the structural part, the first preform including a fibrous reinforcement of short fibres, and the second preform or the structural part comprising a woven fibrous reinforcement, and densification of the first preform of the assembly by infiltration with a molten composition.

A method for manufacturing a turbomachine blade made of ceramic matrix composite material, comprising at least a structural part and a functional part secured to the structural part, the functional part comprising three functional portions:
- a downstream wall, an upstream wall and a root platform of the blade and the structural part comprising a lower platform distinct from the root platform and the method comprising:
- obtaining an assembly comprising a first preform of the functional part that is mounted on a second preform of the structural part or on the structural part, the first preform comprising a fibrous reinforcement of short fibres having a length between 50 μm and 5000 μm, and the second preform or the structural part comprising a woven fibrous reinforcement, and
- densification of at least the first preform of the assembly by infiltration with a molten composition.
