The object of the invention is a process for the production of a panel (7) of composite material with stiffening strips (3), in which a mold (1) is draped with at least one first ply (2) of fibers pre-impregnated with resin, there is emplaced at desired positions on said ply (2) at least one stiffening strip (3), the stiffening strip (3) as well as at least a portion of the remaining surface of said first ply (2) is covered with at least one second ply (4) of fibers pre-impregnated with resin, then a bladder (6) is placed to cover the above elements, a suitable vacuum is established in the space between the mold (1) and the bladder (6), the assembly is then placed in an autoclave to subject it to a pre-established polymerization cycle for the resin, at temperatures and pressures suitable for said resin, and finally the panel is demolded, characterized in that before said emplacement of the stiffening strip (3) and/or of the second ply (4), there is interposed at least one layer, film or the like (5) of a non-adherent material between at least one portion of the surface of the stiffening strip (3) and one and/or the other of said plies (2, 4).
