ABSTRACT:
A rubber composition containing a rubber forming a continuous phase of 100 weight parts; a nylon fiber with fine diameter of 1-15 weight parts by the fiber, the nylon fiber being grafted with a molecular of a rubber capable of co-crosslinking to the rubber forming the continuous phase; and a short fiber of 1-30 weight parts is used to at least a part of a rubber of a transmission belt. Thus, high anisotropy in modulus of elasticity in the transmission belt is maintained. Further, stress concentration at an interface of the short fiber and the rubber is distributed to enhance the strength, elasticity and flex fatigue resistance.
