Abstract

La présente invention concerne un procédé d'obtention d'un panneau sandwich comportant les étapes suivantes : - on empile, sur un moule (4), les différentes couches d'une structure sandwich (1), celle-ci étant constitué par une âme centrale (3) en mousse ou alvéolaire, ladite âme (3) étant encadrée de part et d'autre par un tissu pré-imprégné d'une résine ; - on recouvre ladite structure sandwich (1) par au moins une couche d'un matériau apte à permettre un maintien uniforme du vide et une évacuation de l'eau produite lors de l'étape de polymérisation de la résine, ladite couche de matériau étant disposée sur la face de la structure sandwich (1) opposé à celle reposant sur ledit moule (4) ; on recouvre l'ensemble d'une bâche apte à permettre de faire le vide de sorte à maintenir la structure sandwich (1) sous pression ; - on procède à la polymérisation pour obtenir le panneau sandwich ; ledit procédé étant caractérisé en ce que l'on effectue au moins une rainure transversale (5) et/ou au moins une rainure longitudinale (6) au niveau de la face (7) de l'âme centrale (3) du côté du moule (4).
