A process for the production of a panel of composite material with stiffening strips, in which a mold is draped with at least one first ply of fibers pre-impregnated with resin, there is emplaced at desired positions on said ply at least one stiffening strip, the stiffening strip as well as at least a portion of the remaining surface of the first ply is covered with at least one second ply of fibers pre-impregnated with resin, then a bladder is placed to cover the above elements, the assembly is then placed under vacuum and then in an autoclave to polymerize the resin. Before emplacement of the stiffening strip and/or of the second ply (), there is interposed at least one layer () of a non-adherent material between at least one portion of the surface of the stiffening strip and one and/or the other of the plies.
