Rubber-reinforcing carbon fiber cord and method for producing the same

Abstract

To provide a rubber-reinforcing cord having good adhesion to rubber and exhibiting excellent fatigue resistance to stress deformation such as bending deformation, and a method for producing the same. Disclosed a rubber-reinforcing carbon fiber cord in which a resin composition containing a styrenic thermoplastic elastomer resin modified with maleic acid or the like adheres to a carbon fiber bundle that the number of filaments is from 500 to 50,000. The styrenic thermoplastic elastomer resin is preferably a styrene-terminated ethylene-butylene copolymer resin, and the resin composition preferably contains at least one sticky resin of a hydrogenated terpene resin, a β-pinene resin and a terpene resin.
