Abstract
The present application relates to a blade of a rectifier of a low pressure compressor of an axial turbomachine. The blade can also be a rotor and/or turbine blade. The blade includes a composite material with a matrix and a reinforcement comprising a mesh with rods. The rods of the reinforcement are connected to each other and are distributed throughout the volume between the pressure side surface and the suction side surface of the blade. The mesh forms a three-dimensional structure extending over the majority of the thickness of the blade between the pressure side surface and the suction side surface and/or the majority of the length of the blade between the leading edge and the trailing edge. The present application also relates to an iterative method for manufacturing a blade composite where the reinforcement is formed by additive layer manufacturing based on titanium powder and then placed in an injection mold.
