PROCESS OF MAKING A LAYERED STRUCTURE AND AIRCRAFT EQUIPPED WITH SUCH A STRUCTURE

To produce a layered structure (1) which includes a panel (2) made of composite materials applied against at least one metal plate (3), the panel and the plate are stacked, then the stack is bored to produce a fastening borehole, and a fastening rod (8) is inserted into the borehole and the fastener...

Zusammenfassung:	To produce a layered structure (1) which includes a panel (2) made of composite materials applied against at least one metal plate (3), the panel and the plate are stacked, then the stack is bored to produce a fastening borehole, and a fastening rod (8) is inserted into the borehole and the fastener is secured. In the invention, during boring, negative play is created between the bore diameter and the diameter of the fastener such that when the fastener is inserted, it is inserted from the metal plate. By doing so, it is shown that positive interference is caused, promoting the durability of the fastener. Pour réaliser une structure (1) stratifiée qui comporte un panneau (2) en matériaux composites plaqué contre au moins une plaque (3) de métal, on présente le panneau et la plaque en empilement, on perce l'empilement pour former un alésage de fixation, on introduit une tige (8) de fixation dans l'alésage, et on fixe la fixation. Dans l'invention, lors du perçage, on réalise un jeu négatif entre un diamètre de l'alésage et un diamètre de la fixation, et lors de l'introduction de la fixation on l'introduit à partir de la plaque en métal. On montre qu'en agissant ainsi, on provoque une interférence positive favorable à la pérennité de la fixation.
