Abstract
On élimine un écoulement de résine dans les cellules d'une structure nid d'abeille en sandwich en utilisant un adhésif (108) sous forme de film non renforcé, une couche barrière (110) et une couche adhésive (112) renforcée par un renfort tissé entre le stratifié composite (102) et le noyau (106). On obtient des panneaux de qualité supérieure, allégés, aux caractéristiques mécaniques améliorées et d'une tenue structurelle plus aisément prévisible en laissant de la résine dans le stratifié plutôt qu'en la laissant se perdre dans les cellules du noyau. On diminue l'écrasement du noyau et le plissement des couches dans une structure composite nid d'abeille en sandwich en empêchant le glissement des couches d'arrimage par rapport au mandrin et de l'une par rapport à l'autre durant le durcissement à l'autoclave et l'on obtient, de la sorte, des panneaux de qualité supérieure, allégés, aux caractéristiques mécaniques améliorées et d'une tenue structurelle plus aisément prévisible. Le procédé consiste à apposer un adhésif sous forme de film sur les couches d'arrimage sur le contour de la partie extérieure au bord de coupe net. Durant le chauffage à l'autoclave et avant l'application d'une pression élevée sur la structure composite, l'adhésif sous forme de film durcit pour constituer une liaison solide entre les couches et avec le mandrin. Lorsqu'une certaine pression est appliquée, les couches d'arrimage sont fixées ensemble et sur le mandrin afin d'empêcher tout glissement entre les couches du panneau.
