Original Abstract Submitted
A method for manufacturing an inter-blade platform of a turbomachine fan, the platform including a base including a first and a second sacrificial lateral edge having a thickness smaller than that of the central part of the base, the method including the production of a preform of the platform by three-dimensional weaving including a central part portion and two sacrificial edge portions, the thickness of which is smaller than that of the central part portion, the difference in thickness between the lateral edge portions and the central part portion being achieved by withdrawing a plurality of weft yarns located outside the central part portion and not being woven with warp yarns.
