A method of manufacturing a composite material, the method comprising: providing a first layer (14) of CNTs reinforcement elements (13) with liquid matrix material in interstitial gaps between the reinforcement elements; dipping a second layer of reinforcement elements into the liquid matrix material in the interstitial gaps such that the reinforcement elements in the second layer become partially embedded in the first layer ofreinforcement elements and partially protrude from the first layer of reinforcement elements, impregnating the protruding parts of the reinforcement elements in the second layer with liquid matrix material; and curing the liquid matrix material.

L'invention concerne un procédé de fabrication d'un matériau composite. Le procédé comprend les étapes consistant à : utiliser une première couche d'éléments de renfort avec un matériau de matrice liquide dans les espaces interstitiels entre les éléments de renfort ; tremper une seconde couche d'éléments de renfort dans le matériau de matrice liquide dans les espaces interstitiels de manière à ce que les éléments de renfort de la seconde couche soient partiellement incorporés dans la première couche d'éléments de renfort et dépasse partiellement de la première couche d'éléments de renfort ; imprégner les parties qui dépassent des éléments de renfort de la seconde couche avec le matériau de matrice liquide ; et durcir le matériau de matrice liquide.
