  • Using plasma drag particulate accelerator and atomic oxygen device based on PIG ion source, the first experiment was carried out about the combined effect of small debris and atomic oxygen on both the standard Kapton and Kapton with aluminum film. The result indicates that hypervelocity impact by particulate can accelerate the erosion effect of atomic oxygen on both Kapton and Kapton with aluminum film. The combined effect of hypervelocity impact and atomic oxygen is more important on Kapton with aluminum film than Kapton without film. This is because the impact by hypervelocity particles can destroy the aluminum film which prevents the atomic oxygen from eroding Kapton. So when consider the atomic oxygen effect on Kapton with aluminum film, the combined effect of hypervelocity impact by space debris and atomic oxygen should not be neglected. As a result, this effect is a threat to the life-span and credibility of spacecraft, which will restrict the development of high credibility and long life spacecraft.
