Abstract
The process produces a sandwich composite panel including at least one cellular core having on its faces skins of fiber/resin composite material which are fastened to the cellular core. At least one strip of composite material is formed, the profile of which corresponds to that of the peripheral flank of the panel preform. The strip is applied against the flank of the panel preform. The preform, provided with at least one such strip on its border, is subjected to a temperature, rise, without positive pressure being applied, until the resin of the strip has cured and then, after the curing of the strip and before the curing of the resin of the skins, is subjected to the continuation of the temperature rise, with positive pressure being applied.
