Abstract: In the method of fastening aircraft parts together, the following steps are performed: crimping an element onto at least two parts so as to fasten them together; and screwing a screw into the element through at least one other part so as to fasten all the parts together and so as to place a head of the screw in a flush position relative to the other part.

Abstract: A process for the production of a stiffened panel made of composite material, includes the stages of depositing the fibers that constitute the panel on a rigid device (50), depositing the at least one stiffener (14), covering the unit with a sealed wall connected to the rigid device (50) on the periphery of the panel, and then polymerizing, and providing—for each stiffener (14)—a rigid counter-mold in contact with the convex surface of the stiffener (14), using—for each stiffener (14)—a core (66) in the form of a flexible and sealed bladder, and subjecting the interior of the bladder to pressure during polymerization for compacting the stiffener (14) and the panel.
