L'invention concerne un agencement permettant de garnir l'intérieur d'un véhicule de transport de passagers, par exemple un aéronef, de plusieurs panneaux en nid d'abeilles (22) disposés côte à côte. Chaque panneau en nid d'abeilles (22) comporte au moins deux couches de revêtement (44), en plastique armé de fibres, collées respectivement au-dessus et au-dessous d'au moins une âme en nid d'abeilles (46), formant ainsi un stratifié, lequel stratifié est agencé de manière à s'étendre parallèlement au revêtement extérieur de l'aéronef dont il suit la courbure. La structure en nid d'abeilles utilisée est constituée d'âmes en nid d'abeilles en papier ou en aramide ou encore d'une association des deux types d'âme. En variante, des couches isolantes supplémentaires en plastique armé de fibres sont collées sur la surface extérieure de la couche de revêtement (44) respective supportée au-dessus et au-dessous de la structure en nid d'abeilles. Par ailleurs, la configuration stratifiée de ce revêtement en nid d'abeilles peut comporter des âmes en nid d'abeilles supplémentaires venant s'empiler et se coller sur le panneau en nid d'abeilles utilisé.
