【 摘 要 】

The mechanical property of polyimide film(PI) in electron, proton, near ultraviolet and far ultraviolet was studied by Φ800 combined space radiation test facility of Beijing Institute of Space Environment Engineering, the degradation of mechanical property of polyimide film was tested by Electronic tensile testing machine. The tensile strength and the rupture elongation of polyimide film decrease with the increase of electron or proton radiation, while tensile strength and the rupture elongation of polyimide film decrease firstly and then increase with near ultraviolet irradiation.
