Method for fabricating a turbomachine blade made from a composite material

A method for manufacturing a turbomachine blade made of ceramic-matrix composite material comprising an airfoil and a platform, the method comprising:

• the production of a first fibrous preform comprising ceramic fibers, the first fibrous preform forming an airfoil preform;
• the production of a second fibrous preform comprising ceramic fibers, the second fibrous preform comprising a housing, the second fibrous preform forming a platform preform;
• the production of a strand of ceramic fibers;
• the consolidation of the first fibrous preform in one piece, of the second fibrous preform in one piece and of the strand of ceramic fibers to form a first consolidated preform, a second consolidated preform comprising a housing and a consolidated strand;
• the assembly of the first consolidated preform and of the second consolidated preform, by engagement and cooperation of the first consolidated preform in the housing, the consolidated strand being interposed between the first consolidated preform and the second consolidated preform;
• the co-densification of the assembly to form the turbomachine blade.
