Abstract: A method for manufacturing a cellular structure having first and second faces, rows of cells each alternatingly having first cells, which are open in the direction of the first face, second cells, which are open in the direction of the second face, and also third cells formed between each row of cells, each row of cells comprising first and second strips of material placed against one another. The first and second strips of material are shaped by bending. By contrast to plastic deformation, shaping by bending makes it possible to expand the choice of materials and thicknesses for the first and second strips of material. An advantageous cellular structure is thus obtained as well as an acoustic absorption coating comprising such a cellular structure.

Abstract: An assembly jig for a cellular structure made from strips of material placed adjacent to each other and joined together so as to form first and second cells, opening on the first and second faces of the cellular structure, respectively. This assembly jig includes a housing delimited by a base and first and second side faces, configured for housing the strips of material of a cellular structure to be formed, superimposed on each other, a plurality of pins configured to be positioned between the superimposed strips of material in the first and/or second cells. An assembly device comprising the jig, and a method for manufacturing a cellular structure using the jig are also provided.
