A process for manufacturing a composite panel includes providing at least one first ply of a woven or nonwoven dry material, the first ply defining a peripheral contour. A structuring element is placed inside the peripheral contour of said first ply, over at least one portion of this peripheral contour. A second ply of a woven or nonwoven dry material is placed so that said second ply covers both the first ply and the structuring element, or at least one portion of the first ply, which includes the peripheral contour, is folded over to cover the structuring element, and a second ply of a woven or nonwoven dry material is placed so that said second ply covers the first ply, but not the structuring element. A thermoplastic or thermosetting resin is injected into mould containing the stack to impregnating the plies. The impregnated piles are pressed into a composite panel.
