The subject of the invention is an acoustic treatment panel comprising, beginning on the inside and working outwards, a reflective layer (50), at least one honeycomb structure (52), and at least one acoustically resistive structure (54) forming an aerodynamic surface, said panel being connected along an edge to at least one second panel (46), and being characterized in that it comprises, on the edge which overlaps said at least one second panel, a reinforcement (60) in between the reflective layer (50) and the acoustically resistive structure (54) forming the aerodynamic surface, which reinforcement absorbs loads between said layer (50) and said structure (54).

L'objet de l'invention est un panneau pour le traitement acoustique comprenant, de l'intérieur vers l'extérieur, une couche réflectrice (50), au moins une structure alvéolaire (52) et au moins une structure acoustiquement résistive (54) formant une surface aérodynamique, ledit panneau étant relié au niveau d'un bord à au moins un second panneau (46), caractérisé en ce qu'il comprend, au niveau du bord chevauchant avec ledit au moins un second panneau, un renfort (60) intercalé entre la couche réflectrice (50) et la structure acoustiquement résistive (54) formant la surface aérodynamique, ledit renfort assurant la reprise des efforts entre ladite couche (50) et ladite structure (54).
