1. A method for manufacturing a cellular structure having first and second faces and also rows of cells each alternatingly comprising first cells, which are open towards the first face, and second cells, which are open towards the second face, the cellular structure likewise comprising, between each row of cells, third cells, which are open towards the first and second faces; the method for manufacturing the cellular structure comprising:
shaping first and second strips of material by bending in order to obtain, for each first and second strip of material, first and second recessed shapes and also joining zones separating the first and second recessed shapes, the pluralities of the first and second strips of material being identical, and
assembling the first and second strips of material so as to form the cellular structure by holding and connecting the joining zones of the first strips of material against the joining zones of the second strips of material, the first and second recessed shapes alternating and being arranged so as to form the first and second cells and also the third cells, and
wherein, during the step of shaping by bending of the first and second strips of material, each first strip of material is shaped by bending so as to also obtain a first channel and each second strip of material is shaped by bending so as to also obtain a second channel, the first and second channels forming ducts, each of which connects a pair of the first cells and the second cells.
