Abstract (en)

[origin: WO2022238637A1] The invention relates to a composite material based on a rubber composition based on at least one elastomer, a reinforcing filler, a crosslinking system and at least one metallic reinforcing element embedded in said rubber composition, said composite material being obtained by a method comprising at least one step of generating an atmospheric plasma, a step of contacting the surface of the metallic reinforcing element with the atmospheric plasma, and a step in which the metallic reinforcing element is embedded in the rubber composition so as to obtain the composite material.
