Abstract
The subject of this invention is to provide a rubber reinforcing cord that can be suitably used as a reinforcing material of rubber materials such as tires, belts and hoses and is excellent in fatigue resistance. This invention is a rubber reinforcing cord, characterized in that a carbon fiber bundle having a breaking extension of 1.7% or more is impregnated with a resin composition containing a rubber latex, and that the initial gradient (dM/dy) at y=0 of the bending load M—deflection y curve of the cord is 1000 N/m or less. This invention is a substantially twist-less rubber reinforcing cord, characterized in that a carbon fiber bundle having a breaking extension of 1.7% or more is impregnated with a resin composition containing a rubber latex, and that the number of twist of the cord is 10 per meter or less.
