Metal mesh material is the one of potential materials because of both lightweight and flexible. The purpose of this study is to investigate protection capability of metal mesh materials. In this study selected were two kinds of metal mesh materials; Stainless and Copper. Hypervelocity impact tests were carried out by a two-stage light gas gun using a polycarbonate projectile with 10 mm in diameter, 10 mm in thickness and 1 g in mass. The impact velocity of the projectile was 3.2 km/s. The images of fragments produced by the impact of projectile were taken by two X-ray cameras. Two cameras had delay time. The images were analyzed and the kinetic energy of fragments was calculated. Evaluated was protecting ability of metal mesh material quantitatively compared the kinetic energy before with after impact. As the result, it was found that a stainless mesh with 1 mm in thickness reduced kinetic energy by up to 38 percent but a copper mesh reduced by up to 97 percent. The stainless mesh generated fragments with large degree in spray angle in the rear of the mesh and reduced velocity by up to 48 percent. The copper mesh generated fragments with small degree and reduced velocity by up to 97 percent. The experimental result showed that the metal mesh material is available as a first bumper material. In addition, mesh materials may reduce the total weight of debris shields drastically.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047275022","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東海大学 大学院工学研究科"},{"subitem_text_value":"東海大学 総合情報センター"},{"subitem_text_value":"九州工業大学 工学部　機械知能工学科"},{"subitem_text_value":"東海大学 大学院工学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokai University Graduate School of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Tokai University Information Science Laboratory"},{"subitem_text_language":"en","subitem_text_value":"Kyushu Institute of Technology Department of Mechanical & Control Engineering, Faculty of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Tokai University Graduate School of Engineering"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"東出, 真澄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"赤星, 保浩"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"遠山, 文雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Higashide, Masumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akahoshi, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Toyama, Fumio","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"金属メッシュ","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙デブリ","subitem_subject_scheme":"Other"},{"subitem_subject":"超高速衝撃","subitem_subject_scheme":"Other"},{"subitem_subject":"航空宇宙環境","subitem_subject_scheme":"Other"},{"subitem_subject":"ガス銃","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃試験","subitem_subject_scheme":"Other"},{"subitem_subject":"ステンレス鋼","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃損傷","subitem_subject_scheme":"Other"},{"subitem_subject":"metal mesh","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"space debris","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hypervelocity impact","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerospace environment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gas gun","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"impact test","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stainless steel","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"impact damage","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"デブリ衝突を模擬した金属メッシュ材料への衝突実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"デブリ衝突を模擬した金属メッシュ材料への衝突実験"}]},"item_type_id":"5","owner":"1","path":["1578","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"8138","relation_version_is_last":true,"title":["デブリ衝突を模擬した金属メッシュ材料への衝突実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:27:52.570021+00:00"}
