The invention relates to a method for providing the outer walls of a tank of a space launcher having a smooth structure with a composite sandwich layer having mechanical functions. The method consists of positioning, on the entire surface to be covered, a low-density reinforcement layer (10) consisting of fibers. Said reinforcing layer (10) is then impregnated with a resin, and then the latter is polymerized, preferably in a vacuum. A tear-off film (7) makes it possible to remove the elements that were used to implement the reinforcement layer and that no longer have to be part of said layer. The invention can be used in the cryogenic tanks of space launchers.
