Abstract
The object is to provide a carbon fiber-reinforced rubber material which is superior in heat resistance, water resistance, and dimensional stability and exhibits resistance to fatigue from flexing at a practical level. The present invention relates to a prepreg comprising a liquid rubber composition having a viscosity in a range of 0.01 Pa·s to 100 Pa·s at 70° C. and substantially containing no solvent, the liquid rubber being impregnated into a reinforcing fiber, and relates to a fiber-reinforced rubber material comprising the prepreg in which the liquid rubber is crosslinked. Also, the present invention relates to a fiber-reinforced rubber material comprising a substrate comprising a rubber component, the substrate being reinforced by a core material comprising a prepreg of a reinforcing fiber impregnated with the same rubber component.
