Abstract: The BMP370 polyimide of high-temperature resistant PMR-15 model is a new third-generation polyimide resin. The composites curing process of the BMP370 and the T300 carbon fiber includes the amidation, the imidization and the cure cross-linking reaction. The volatiles content and the vacuum control during the curing is studied particularly. The mechanical, high-temperature mechanical and physical properties of laminates are analyzed. The development direction used in model application was proposed.
