The present invention concerns a composite plate (1) comprising a first cover layer (3), a second cover layer (5), and a core layer (7) arranged between the first and the second cover layers (3, 5) and having a plurality of cells (9) which are at least partially open towards the first cover layer (3) and which are separated from each other by walls as well as a method of draining such a composite plate (1). In order to provide such a composite plate (1) in which improved resistance to ingress of liquid or formation of liquid accumulations is guaranteed in a simple and continual fashion it is proposed that a draining layer (13) is provided in the first cover layer (3), wherein the cells (9) are at least partially covered by the draining layer (13).

La présente invention concerne une plaque composite (1) comprenant une première couche de revêtement (3), une deuxième couche de revêtement (5) et une couche centrale (7) disposée entre les première et deuxième couches de revêtement (3, 5) et comportant une pluralité de cellules (9) qui s'ouvrent au moins partiellement vers la première couche de revêtement (3) et qui sont séparées les unes des autres par des parois, ainsi qu'un procédé de drainage d'une telle plaque composite (1). Pour obtenir une telle plaque composite (1) dans laquelle une résistance améliorée à l'entrée de liquide ou à l'accumulation de liquide est assurée d'une manière simple et continue, on propose de former dans la première couche de revêtement (3) une couche de drainage (13) qui recouvre au moins partiellement les cellules (9).
