Abstract: A method of manufacturing an acoustic treatment panel including at least one cellular structure with at least one anchor layer at the level of at least one of its faces. The anchor layer includes at least one adhesive sheet chosen from an adhesive film or a ply of pre-impregnated adhesive fibers in contact with the cellular structure. The method of manufacture includes, before the integration of the cellular structure in an acoustic treatment panel, a step of placing the anchor layer on a support, the adhesive sheet being the last to be placed, a step of placing the cellular structure on the anchor layer in contact against the adhesive sheet, and then a step of polymerization of the anchor layer and of the cellular structure.
