A blade includes a fibrous reinforcement having a three-dimensional weave densified by a matrix, the fibrous reinforcement including, in a single woven piece, a root and an aerodynamic profile part extending along a longitudinal direction between the root part and a blade tip portion and along a transverse direction between a leading and a trailing edge portion. The profile part includes first and second suction side and pressure side faces. The fibrous reinforcement includes a separation forming a housing inside the fibrous reinforcement, a bladder filled with a shaping foam being present in the housing. The separation extends over a separation zone inside the profile part of the fibrous reinforcement comprised between the root part and the blade tip portion in the longitudinal direction and between the leading and the trailing edge portion in the transverse direction. The separation opens to the outside of the profile part.
