A honeycomb core is built up of strips made with a material such as cellulose material, the strength and/or the shape of which is sensitive to the action of moisture. The strips are built up in layers and comprise a layer of plastic. The plastic layer can be located between two layers of the moisture-sensitive material and be integral with this. With this honeycomb core a honeycomb panel in the shape of a sandwich construction can be built up, which comprises two cover plates made with a material such as cellulose material, the strength and/or the shape of which is sensitive to the action of moisture, which cover plates form panel faces, between which the core is glued, in which at least one of the cover plates is moisture-proof. At least one of the cover plates can be built up in layers and can comprise a layer of plastic. The cover plate concerned can comprise two layers of the moisture-sensitive material, between which the plastic layer thereof is located which is integral with this.
Ame en nid d'abeilles constituée de bandes d'un matériau tel que la cellulose dont la résistance et/ou la forme varient en fonction de l'humidité. Lesdites bandes sont disposées en couches parmi lesquelles se trouve une couche de plastique qui peut être placée entre deux couches du matériau hydrosensible ou leur être intégrée. On peut donc ainsi former un panneau de nid d'abeille à construction en sandwich dont l'âme est en nid d'abeille et dont les plaques de couverture, collées à l'âme, sont faites du susdit matériau en cellulose, dont la résistance et/ou la forme sont sensibles à l'humidité lesdites joues formant des faces de panneau, au moins une desdites joues étant étanche à l'humidité. L'une au moins des plaques de couverture peut consister en plusieurs couches, dont une en plastique. La plaque de couverture concernée peut comprendre deux couches du matériau hydrosensible, la couche de plastique se trouvant entre elles ou leur étant intégrée.
