CA 2523008

An object with a stratified composite material comprises a first non-metallic layer and a second metallic layer applied to the first non-metallic layer which contains at least one polymer. The boundary layer between the non- metallic layer and the metallic layer has a roughness with an Ra value of maximum 5 µm, an adherence of at least 12 N/mm2 and a standard adherence deviation of maximum 25 % of the mean arithmetic value, distributed over the surface of the composite material as six different measurement values. Also disclosed is a method for producing said object and its use.

L'objet décrit comprend un matériau composite stratifié avec une première couche non métallique et une seconde couche métallique déposée sur la première couche non métallique, qui contient au moins un polymère. La limite entre la couche non métallique et la couche métallique a une valeur de rugosité Ra de maximum 5 mu m, une adhérence d'au moins 12 N/mm<2> et un écart type de l'adhérence de 25 % au maximum de la valeur arithmétique moyenne, sous forme de six valeurs différentes de mesure distribuées sur la surface du matériau composite stratifié. L'invention concerne également un procédé de fabrication de cet objet et son utilisation.
