Abstract
The invention provides a rubber reinforcing cord that can be suitably used as a material for reinforcing rubber materials such as tires, belts and hoses and is excellent in fatigue resistance. This invention is also a rubber reinforcing cord in which a carbon fiber bundle is impregnated with a resin composition comprising a rubber, wherein the elastic modulus of dried film of the rubber latex at 25° C. (G′) is 0.4 MPa or less, and the carbon fiber bundle has a knot-breaking strength of 500 MPa or more.
