    摘要: The invention relates to a honeycomb core structure (202) for use in a structural panel for a jet engine nacelle, comprising at least one block with a honeycomb core (A, B) having a central part (5a, 5b) with core honeycomb cells (7a, 7b) and at least two lateral parts (9a, 9b) each comprising a number of honeycomb joining cells (11a, 11b) of which at least one part of the honeycomb joining cells (11a, 11b) has at least one additional wall (201a, 201b) to form a join, the honeycomb core block(s) (A, B) being connected by at least one joint zone (213) formed by punching two additional walls (201a, 201b) superimposed one o the other and provided by honeycomb joining cells (11a, 11b) belonging to the distinct lateral parts (9a, 9b). The invention further relates to a structural panel and a nacelle comprising such a structure (202) and a method for producing such a structure (202).
