Abstract: A fiber-reinforced polyimide resin molded article and a production process therefor. After a prepolymer of an addition reaction type polyimide resin and functional fibers are dispersed and kneaded together, the kneaded product is kept at a temperature not lower than the heat curing start temperature of the reaction type polyimide resin for a fixed amount of time or mixed with a thickener to increase its viscosity, and shaped at a temperature not lower than the heat curing start temperature of the reaction type polyimide resin to obtain a molded article having excellent sliding performance with a limit PV value of not less than 3, 000 kPa · m/s and excellent shape stability during molding and containing the functional fibers dispersed in the polyimide resin.
