The invention relates to a method for producing, planar, simple or doubly folded core com-posites (1, 23) with at least one folded honeycomb core (4, 19). A hardening and later removable core filler (15, 16) is introduced into the through drainage channels (5, 6) of the folded honeycomb core (4, 19) before application of the initially unhardened surface layers (2, 3, 13, 22) in order to prevent a penetration of the cover layers, (2, 3, 13, 22) into the channels (5, 6) of the folded honeycomb core on the application and/or hardening of the surface layers (2, 3, 13, 22) and to achieve surfaces of the core composite (1, 23) without edges or polygons.
L'invention concerne un procédé de fabrication de structures sandwichs (1, 23) planes, à simple courbure ou à double courbure comprenant au moins un noyau alvéolaire plissé (4, 19). Selon ce procédé, avant l'application des couches de recouvrement (2, 3, 13, 22) initialement non durcies, une matière de remplissage de noyau (15, 16) durcissable pouvant être retirée ultérieurement est introduite dans des canaux (5, 6) continus du noyau alvéolaire plissé (4, 19), ces noyaux pouvant être drainés, de manière à empêcher que les couches de recouvrement (2, 3, 13, 22) ne s'étendent dans les canaux (5, 6) du noyau alvéolaire plissé lors de la disposition et/ou du durcissement desdites couches de recouvrement (2, 3, 13, 22) et de sorte que la structure composite (1, 23) présente des surfaces sans arêtes et sans polygones.
