Abstract

- L'objet de l'invention est un procédé de fabrication d'un panneau à propriétés structurale et acoustique du type sandwich constitué d'une âme à structure alvéolaire ouverte (1), caractérisé en ce qu'il consiste à réaliser une première et une seconde peau (2,3) par drapage et pressage à chaud d'au moins deux plis de tissu de fibres minérales ou synthétiques imprégnées d'une résine thermoplastique, à réaliser dans l'une des peaux (2,3) des perforations (4) d'un diamètre de l'ordre de 0,5 à 1,5 mm, avec une proportion de vide à la surface de la peau de l'ordre de 10 à 25%, à appliquer sur l'une des faces des peaux, après préparation, un revêtement de colle époxy, à former un sandwich comprenant ladite âme à structure alvéolaire ouverte (1) avec les deux peaux (2,3) sur ses faces opposées, puis à presser à chaud le sandwich à des fins de polymérisation de la colle dans des conditions de température, pression et durée évitant toute obstruction même partielle des perforations de la peau perforée (3). - Application notamment à des cloisons de fuselage d'aéronefs.
