Method of molding aromatic polyimide resin

Abstract

A method of molding an aromatic polyimide resin, comprising compression molding an aromatic polyimide resin composition powder comprising an aromatic polyimide resin and a fluorine resin added thereto, and then sintering the compression molded product in a mixed gas atmosphere of oxygen and inert gas, having the oxygen concentration of 0.1 to 10% at 360.degree. to 480.degree. C., or sintering the compression molded product in an inert gas atmosphere and then heat treating the same in a mixed gas atmosphere of oxygen and inert gas at 360.degree. to 480.degree. C. This method can solve the problems on color shade and strength due to sintering in the case of molding an aromatic polyimide resin having a fluorine resin added thereto, and can provide a polyimide molding having excellent quality.
