Abstract

Panneau renforcé à structure alvéolaire comprenant au moins une zone de liaison présentant une surépaisseur et aéronef comprenant au moins un tel panneau renforcé L'invention a pour objet un panneau renforcé d’un aéronef comprenant au moins une structure alvéolaire (46) comportant une paroi (48) présentant des première et deuxième faces (48.1, 48.2) ainsi qu’un réseau de nervures (50) intégrales à la paroi (48), positionnées sur la première face (48.1) de la paroi (48) et délimitant des alvéoles (54), caractérisé en ce que la paroi (48) de la structure alvéolaire (46) comprend au moins une zone de liaison (76) qui présente une surépaisseur (84). Cette solution permet de réduire la masse embarquée et de réduire le temps de fabrication du panneau renforcé. L’invention a également pour objet un assemblage de deux panneaux dont au moins un comprend une structure alvéolaire. Figure 10
