Abstract

L'invention concerne un matériau composite carboné comprenant une charge, consistant en matériau carboné particulaire à caractéristiques physiques prédéterminées, et un liant destiné à lier le matériau carboné particulaire dans une pâte composite sensiblement homogène qui, lorsqu'elle est exposée à l'atmosphère, se fixe et durcit en une couche composite carbonée élastique avec des propriétés présélectionnées de port de charge, de résistance à l'eau et de résistance à la corrosion. L'invention concerne également une couche composite carbonée élastique et un procédé de production d'une couche composite carbonée élastique.
