A cutting table for cutting out a fiber preform obtained by three-dimensional weaving and having two portions that are connected together by at least one zone of non-interlinking and that present outlines of different shapes, includes a tabletop provided with a recess for receiving one of the portions of the fiber preform to be cut out. The fiber preform is capable of laying flat in the access. The cutting table further includes sacrificial plates for interposing between the portions of the fiber preform for cutting out and for being fastened to the tabletop. The sacrificial plates are capable of covering partially the recess of the tabletop while being fastened to the tabletop. The cutting table also includes a cutting template configured to be pressed against a portion of the fiber preform that is positioned outside of the recess, and a device for applying compacting pressure against the cutting template.
