| Abstract: |
| Objective To provide data support for selection of Kapton/Al film used in spacecraft and theortheoretical supporty for preparation of high performance Kapton/Al material. Methods The Kapton/Al film was radiated by electron from the combined space radiation environment simulator, and tested by the tensile testing machine, and its component and microstructure was analyzed by XPS. Results The tensile strength and the rupture elongation of the Kapton/Al film decreaseds with the increase of tensile ratio and electron dosage. The rupture and cross linkage of molecular bonds in the film, the deoxidation of C—CO, the denitrification of C—N and the increase of C—H percentage are were caused induced by electron radiation. Conclusion Electron radiation on of Kapton/Al film results in the decrease of its mechanical property of it, and the rupture and cross linkage of molecular bonds are is the main cause of its property degradation. |
