A blade of a rotating part of a turbomachine comprising:

• an airfoil made of a composite material comprising a fibrous reinforcement embedded in a polymer matrix, the airfoil comprising a leading edge and a trailing edge;
• a first structural shield applied and attached to the leading edge and a first stiffener formed integrally and in a single piece with the first structural shield, the first stiffener extending between the leading edge and the structural shield;
• and
• a second structural shield applied and attached to the trailing edge, and
• at least one stiffener formed integrally and in a single piece with the second structural shield, said second stiffener extending between the trailing edge and the structural shield.
