Abstract

An aircraft propeller blade including an airfoil-profile structure. The airfoil-profile structure includes at least one fiber reinforcement obtained by three-dimensional weaving of yarns and densified by a matrix, and a shaping part made of cellular rigid material of determined shape, the reinforcement including at least two halves linked together by continuous weaving in the leading edge of the propeller blade, the two halves fitting tightly around the shaping part.
