Abstract

L'invention concerne un procédé de fabrication d'un panneau sandwich composite, le panneau comportant une âme formée d'une pluralité d'alvéoles qui s'étendent verticalement entre une première peau et une seconde peau, caractérisé en ce qu'il comprend au moins une étape de réalisation d'au moins une première bande (20a) et une seconde bande (20b) dans un matériau fugitif, chaque bande (20a, 20b) présentant au moins une empreinte (30a, 30b, 31b) qui comprend une succession de demi-alvéoles alignées, une étape de tapissage qui consiste à tapisser au moins un pli fibreux (34) sur l'empreinte (30a) de la première bande (20a), une étape d'assemblage de la première bande (20a) et de la seconde bande (20b) qui consiste à imbriquer l'empreinte (30a) de la première bande (20a) avec l'empreinte (31b) de la seconde bande (20b), en emprisonnant ledit pli fibreux (34), et une étape de rognage qui consiste à retirer le surplus de matière fongible de l'ensemble des bandes (20a, 20b) formé au cours de l'étape d'assemblage précédente, de façon à former une nouvelle empreinte (38) qui forme une succession de demi-alvéoles (40) alignées.
