| Abstract: | The radiation damage by vacuum ultraviolet (VUV) under the space enviro nment and several types of the vacuum ultraviolet simulation is introduced. The basic structure, the working mechanism and the technical parameters as well as the characters of the gas jet type of vacuum ultraviolet simulator are emphasiz e d. The radiation damage of several materials for space application by vacuum ult raviolet is studied using gas jet type of vacuum ultraviolet simulator. Result s hows that VUV results in remarkable mass loss for the EP and CF/EP, and results in decreasing the mechanical properties and great damage of the fiber and surfa ce of matrix. VUV combined with the cycling temperature has a considerable effec t on the mechanical properties of polyimide coatings for absorbing light. |
