Numerical Simulations of the Combined Effects of Atomic Oxygen and Ultraviolet on Polyimide

Based on a mathematical mode proposed by the authors to describe the physical interactions of atomic oxygen and ultraviolet with polyimide, numerical simulations of their combined radiation effects on polyimide with and without coated layers in Low Earth Orbit (LEO) and ground experiment environment were conducted. The results are consistent with the Long Duration Exposure Facility (LDEF) results, providing a valuable reference for the design of spacecrafts.
