Abstract
The invention relates to a method for manufacturing a structure with cellular cores (202) that can be used in the structural panel of a turbojet nacelle, including at least one block of cellular cores (A, B) having a central portion (5a, 5b) with core honeycomb cells (7a, 7b) and at least two side portions (9a, 9a', 9b, 9b') each including side honeycomb cells (11a, 11b), wherein said method includes the following steps: A) forming junction walls on the side honeycomb cells (11a, 11b), the junction walls being capable of interacting for forming a junction area (213); B) unfolding the junction walls thus formed; and C) joining the walls thus unfolded (46) and belonging to two different side portions (9a, 9b) end-to-end so that said junction walls (46) are fitted together so as to form a junction area (213). The invention also relates to a structural panel and to a nacelle including a structure with cellular cores obtained by said method.
