Title (EN) METHOD FOR PRODUCING THE OUTER LAYER OF A TANK OF A SPACE LAUNCHER
(FR) PROCEDE DE REALISATION DE LA COUCHE EXTERNE D'UN RESERVOIR DE LANCEUR SPATIAL
Abstract:
(EN) 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.
(FR) Le procédé permet de doter les parois externes d'un réservoir de lanceur spatial de structure lisse d'une couche sandwich composite ayant des fonctions mécaniques. Il consiste à poser sur l'ensemble de la surface à recouvrir une couche de renfort (10) de faible densité, composée de fibres. Puis à imbiber cette couche renfort (10) d'une résine, puis à polymériser cette dernière, de préférence sous vide. Un film d'arrachage (7) permet d'enlever les éléments qui ont servi à la mise en œuvre de la couche renfort et qui ne doivent plus en faire partie. Application aux réservoirs cryogéniques des lanceurs spatiaux.
