Beschreibung
Zusammenfassung:	Turbomachine blade (100) made of composite material containing a fibrous reinforcement obtained by the multi-layered weaving of filaments and densified by a matrix. The blade comprises a first part that forms the aerofoil (120), making a single component with at least one second part that forms a blade root (130). The fibrous reinforcing parts corresponding to the first and second parts of the blade (100) are at least partially imbricated in one another, with filaments of the second fibrous reinforcing part penetrating the first fibrous reinforcing part.
