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 (), depositing the at least one stiffener (), covering the unit with a sealed wall connected to the rigid device () on the periphery of the panel, and then polymerizing, and providing—for each stiffener ()—a rigid counter-mold in contact with the convex surface of the stiffener (), using—for each stiffener ()—a core () in the form of a flexible and sealed bladder, and subjecting the interior of the bladder to pressure during polymerization for compacting the stiffener () and the panel.
