Abstract

The disclosure proposes a method for producing a panel having an outer skin and stiffeners that have a connecting portion, and at least one projecting portion, the method comprising a step of draping layers of fibers over at least one insert such that each layer of fibers has a connecting portion and a portion that projects downwardly from the connecting portion, a step of draping a layer of fibers that forms the outer skin, and a step of bonding the layers of fibers together. The disclosure also provides a device for implementing the method.
