Abstract

La présente invention concerne un ensemble lamifié (20) comprenant un empilement de couches principales (25) et de couches secondaires (30), chaque couche principale (25) comportant un matériau souple et chaque couche secondaire comportant un matériau rigide, ledit empilement s'étendant en envergure selon l'axe d'extension (AX) d'une première couche principale (26) jusqu'à une dernière couche principale (27). Au moins une desdites couches principales (25) a une forme de coiffe de sphère, ladite coiffe de sphère représentant une partie d'une paroi sphérique tronquée par un tube à section non circulaire, ladite section s'étendant selon un premier axe sur une longueur et un selon un deuxième axe perpendiculaire au premier axe sur une largeur, ladite longueur étant supérieure à ladite largeur.
