A number of integrated floor structures (100, 200, 300) made of lightweight composite materials for use in an aircraft are disclosed. Generally, each of such floors includes a top-layer skin (210) , a bottom- layer skin (280) disposed below the top-layer skin and a first structural core (260) disposed between the top- layer skin and the bottom-layer skin, the first structural core being composed of a honeycomb composite material. One or more denser structural cores (230) can also be incorporated at strategic locations.

L'invention concerne une pluralité de structures de plancher intégré (100, 200, 300) constituées de matériaux composites légers et destinées à être utilisées dans un aéronef. En règle générale, chacun de ces planchers comprend une couche de revêtement supérieure (210), une couche de revêtement inférieure (280) disposée sous la couche de revêtement supérieure et une première âme structurelle (260) disposée entre les couches de revêtement supérieure et inférieure, cette première âme structurelle étant constituée d'un matériau composite en nid d'abeilles.
