(57) [Problem] To provide a tire, which exhibits excellent fatigue resistance, An object of the present invention is to provide a rubber reinforcing cord and a fiber reinforced rubber material using carbon fiber, which can be preferably used for various rubber materials such as a belt and a hose. A rubber reinforcing cord according to the present invention is characterized in that a carbon fiber bundle having a knot strength of 500 MPa or more is impregnated with a resin composition containing rubber latex. Further, the fiber-reinforced rubber material of the present invention is characterized in that a base material containing rubber is reinforced by the rubber reinforcing cord. |
