Although many researches regarding LEO environment on physical and chemical properties of polymers were reported, those on mechanical behaviors are still insufficient. For the long term use of polymers in LEO, it is necessary to elucidate the strength properties systematically. This study exposed Poly-ether-ether-ketone (PEEK) films under tensile stresses into LEO by using ISS Russian service module. In parallel, ground tests were carried out by using JAXA facilities, which irradiated AO, UV, and electron beam (EB) to the specimens individually. By comparing the results of flight tests with ground tests, degradation properties and the mechanisms were studied., Physical characteristics: Original contains color illustrations, 資料番号: AA0064307010, レポート番号: JAXA-SP-08-015E}, pages = {73--80}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Effects of LEO environment on mechanical properties of PEEK films under tensile stress}, volume = {JAXA-SP-08-015E}, year = {2009} }
