Method for producing a curved honeycomb structure made from composite material
The invention relates to a method for producing a curved honeycomb structure, comprising the following steps: producing a deployable fibrous structure (100) by means of the multi-layer weaving of a plurality of layers of warp yarns and a plurality of layers of weft yarns, said fibrous structure comprising separating zones which extend through the thickness of the fibrous structure and are spaced from one another by linking portions between multiple layers of weft yarns, the linking portions being offset by one or more weft yarns in a direction parallel to that of the layers of weft yarns between each series of weave planes; impregnating the fibrous structure (100) with a precursor resin of a pre-determined material; deploying the fibrous structure (100) on a holding tool (50) such as to form, in the fibrous structure, a cell in each separating zone, said tool also having a curved shape corresponding to the shape of the cell structure to be produced; polymerizing the resin of the fibrous structure such as to form a curved cell structure comprising a plurality of cells.
