Blade with composite structure having improved ply drop orientation

A blade for a turbomachine fan, comprising a root configured to be attached to a fan disk and a vane capable of extending in an air flow and defining a blade head opposite the root, the blade having a pressure side, a suction side, a leading edge and a trailing edge, the blade being elongated in a longitudinal direction extending from the root to the blade head, said longitudinal direction being substantially orthogonal to a chord direction extending from the leading edge to the trailing edge, the blade being composed at least in part of a structure made of composite material comprising a fiber reinforcement obtained by three-dimensional weaving and a matrix in which the fiber reinforcement is embedded, the fiber reinforcement comprising a plurality of intermingled plies, each ply being formed of warp yarns extending substantially orthogonally to the chord direction and weft yarns extending substantially orthogonally to the longitudinal direction, the warp yarns and weft yarns including incomplete yarns that each have a terminal end on the pressure side or the suction side, the pressure side and the suction side each have at least one ply drop line connecting the terminal ends of the incomplete yarns of the same ply,

• wherein the ply drop lines are in greater number on the pressure side than on the suction side in a low region of the blade between the root and 30% of a height of the blade and/or in an extended region of the blade between the root and 70% of the height of the blade.
