FIBER-REINFORCED POLYIMIDE COMPOSITE MATERIAL, AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To inexpensively provide a fiber-reinforced polyimide composite material that has excellent heat resistance and strength, and enables a laminate molding to be easily produced.SOLUTION: A fiber-reinforced polyimide composite material comprises a core layer in which a sheet-like reinforced fiber is impregnated with a high heat-resistant polyimide resin showing no flowability even in a temperature area of 300°C or more, and a heat-fusible surface layer composed of a thermoplastic polyimide resin having a glass transition point (Tg) in the range of 100°C-400°C.
