Abstract
A fiber-reinforced rubber composition capable of providing a vulcanizate having an excellent strength and modulus and a production process thereof. This fiber-reinforced rubber composition includes fine short fibers of thermoplastic polymer having ##STR1## groups buried in vulcanizable rubber. The vulcanizable rubber and the thermoplastic polymer are grafted to each other through a resol type alkylphenol formaldehyde resin precondensate or a novolak type phenol formaldehyde resin precondensate at an interface of the fiber. The ratio of the fiber to the vulcanizable rubber (A) 1 to 70 parts by weight based on 100 parts by weight of the rubber in the case of the resol type alkylphenol formaldehyde resin precondensate or (B) 1 to 100 parts by weight based on 100 parts by weight of the rubber in the case of the novolak type phenol formaldehyde resin precondensate.
