The relationship between the polymeric material degradation by atomic oxygen (AO) and tensile load was investigated. AO irradiation experiments were carried out at the facility of National Space Development Agency (NASDA). AO was irradiated to PEEK sheets under tensile stress. After AO exposure, surface observation, reaction efficiency (Re) measurements, and tensile tests were made on the sample. As a result, the following were obtained : (1) The circular irradiated region can be observed on all exposed samples. (2) Re was increased by AO exposure under tensile stress. (3) Conical pits were observed allover on all exposed specimens. (4) Elastic modulus was decreased by AO irradiation and this tendency was enhanced by applied stress. It was clear that stress affected polymer degradation by AO.
