The invention relates to a composite cord (8; 80-82; 90-92) comprising a rubber core (83; 93) and a rubber sheath (84-86; 94-96) enclosing the core at least partially, the compositions of the core and of the sheath being different, said cord being characterized in that the rubber core is based on at least one diene elastomer and more than 30 weight percent of elastomer of a filler A, the particles of which are nanoparticles having an average size by weight of less than 500 nm, and in that the rubber sheath is based on at least one diene elastomer having 0 to less than 30 pce of filler A', the particles of which are nanoparticles having an average size by weight of less than 500 nm, and more than 70 pce of a filler B, the particles of which are particles having a median size by weight greater than 1 µm. |
