With its excellent space environmental resistance properties, polyimide, an organic material, is used to fabricate MLI. However, polyimide is degraded by Atomic Oxygen (AO), which is present in low earth orbit. To reduce degradation of MLI, we have developed AO-resistant materials, AO-resistant polyimide in particular. Our materials are proving themselves through orbital experiments and ground tests. Previous studies have suggested that debris impact on polyimide materials degrades their AO resistance. We evaluated the changes in the tested materials through ground hypervelocity impact tests that simulated debris impacts. In this presentation, we will report our work and the current results.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_4_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_4_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA2230027045","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/00049218","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_4_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構研究開発部門(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構研究開発部門(JAXA)"},{"subitem_text_value":"株式会社エイ・イー・エス"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究所(JAXA)(ISAS)"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Advanced Engineering Services Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"}]},"item_4_version_type_30":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"久保, 優子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"木本, 雄吾"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"梅田, 花織"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"長谷川, 直"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUBO, Yuko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KIMOTO, Yugo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"UMEDA, Kaori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HASEGAWA, Sunao","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-02-28"}],"displaytype":"detail","filename":"AA2230027045.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA2230027045.pdf","url":"https://jaxa.repo.nii.ac.jp/record/49236/files/AA2230027045.pdf"},"version_id":"e23426cc-7237-4d22-b89d-0e74228745f2"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"MLI 用耐AO 性材料に対するデブリ衝突の影響評価の取り組み","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"MLI 用耐AO 性材料に対するデブリ衝突の影響評価の取り組み"}]},"item_type_id":"4","owner":"1","path":["1891","2263"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-02-28"},"publish_date":"2023-02-28","publish_status":"0","recid":"49236","relation_version_is_last":true,"title":["MLI 用耐AO 性材料に対するデブリ衝突の影響評価の取り組み"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T18:39:07.423016+00:00"}
