FIELD: transport.
SUBSTANCE: invention relates to production of vulcanised rubber CVT belt. CVT V-belt has belt body with inclined sides, ply of stretchable cord of helically twisted stretchable cord introduced in belt body, rubber ply above said cord and rubber ply under cord. Stretchable cord consists of twisted unmixed yarn of carbon fibre impregnated with adhesive impregnation. Carbon fibre can have thread diameter of about 6.0-6.4 mcm, modulus of expansion of about 200-300 GPa and tensile strength of 1.9-2.3%.
EFFECT: higher strength.
