Abstract
The present invention relates to a V-ribbed belt that includes carbon-fiber twisted cords as core wires, the V-ribbed belt having a tensile elasticity of 240-500 N/(mm·%), and the core wire diameter of the core wires being 0.6-1.2 mm. The V-ribbed belt may have a tensile strength of 620 N/mm or more per 1 mm width of the belt.
Claims9
A V-ribbed belt comprising a twisted cord comprising a carbon fiber as a core wire, wherein:
- the V-ribbed belt has a tensile elastic modulus of 240 to 500 N/(mm %), wherein the tensile elastic modulus of the V-ribbed belt is an inclination of a straight line in an area of 85-140 N/mm in a stress-strain curve;
- the core wire has a core wire diameter of 0.6 to 1.2 mm;
- and
- the core wire has a pitch that is 0.1 to 0.5 mm larger than the core wire diameter.
