The maximum weight of the satellite is determined by the launch capacity of the rocket. Of course, the weight of the main mirror is limited but larger mirror enable higher resolution observation. A specific stiffness of the mirror material is hence a key factor. Since carbon fiber reinforced polymeric composite material (CFRP) is superior to not only the specific stiffness also in-plane thermal stability, it may be suitable to use as mirror. Before applying CFRP to the mirror, several problems should be solved; one of them is long-term reliability of mirror surface accuracy. It is reported that there exist a \"print-through\" problem for CFRP mirror surface. To address this problem, a lot of works regarding surface coating treatment have been done for the mean time. However, the long-term assurance of the surface roughness has not been discussed nevertheless the mechanical property of CFRP is inherently time-dependent. There is a possibility that the time-dependent deformation of the material deteriorates the mirror surface accuracy. The deformation induced by physical ageing, dewater and internal stress relaxation of the matrix may change the surface accuracy. The deformation induced by temperature change is another problem. In this paper, time and temperature dependence of the surface accuracy is studied for CFRP sandwich mirror. The effect of different surface treatment on the surface accuracy is also investigated.","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: DS0065156001","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Materials System Research Laboratory, Kanazawa Institute of Technology"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"金沢工業大学材料システム研究所"}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-6013","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00027831","subitem_source_identifier_type":"NCID"}]},"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":"小柳, 潤"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒尾, 与史彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"武田, 真一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"宇都宮, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川田, 宏之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koyanagi, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arao, Yoshihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeda, Shinichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Utsunomiya, Shin","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawada, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"高分子系複合材料","subitem_subject_scheme":"Other"},{"subitem_subject":"ハニカムサンドイッチ","subitem_subject_scheme":"Other"},{"subitem_subject":"鏡面精度","subitem_subject_scheme":"Other"},{"subitem_subject":"耐久性","subitem_subject_scheme":"Other"},{"subitem_subject":"Polymer Composities","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Honeycomb Sandwich","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mirror Surface Accuracy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Durability","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Time and Temperature Dependence of Surface Accuracy on CFRP Sandwich Mirror","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Time and Temperature Dependence of Surface Accuracy on CFRP Sandwich Mirror","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"21568","relation_version_is_last":true,"title":["Time and Temperature Dependence of Surface Accuracy on CFRP Sandwich Mirror"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:33:26.235523+00:00"}
