Abstract:

Degradation of macroscopic physical properties resulting from chemical changes in fluorocarbon polymers exposed to ionizing radiation is reviewed. The effects of temperature, ultravioletvisible radiation, and dose rate are considered. Of particular interest are property changes that occur on exposure of these materials to simulated space radiation environments. Results from recent space simulation exposure tests are considered in light of these phenomena. General recommendations are made for the application of existing data to spacecraft problems, as well as for the conduct of future space simulation exposure tests. Author
