C/C composites have not been successfully applied to such a primary structure subjected to dynamic load, but C/C composites are required for this case because high temperature up to 1800K and high value of tensile stress, more than 560MPa, are predicted to be applied to the turbine disk and only material that can endure these environments is a C/C composite. At first, difficulties anticipated for the application of a C/C composite to the turbine disk are discussed in terms of measured thermo-mechanical properties and environmental responce of C/C composites. Low value of interlaminar strength and weekness against oxidation were shown to be major diifficultues and these problems are suggested to be able to be resolved by use of 3-dimensional fabrics as the reinforcement and by application of SiC coating on the surface, respectively. Then the optimum design of the turbine disk made of C/C composites were explored in two kinds of structures, i.e., monolithic and joined. The monolithic structure was assumed to be composed of 3-dimensionally reinforced fabrics and the joined structure divided in to 3 components. Through the discussion, the joined structure was shown to be superior to the monolithic structure, provided that vibration induced by instability can be suppressed. It is due to the reason that in the joined structure the optimum arrangement of reinforcing fiber can be easily made obeying the stress distribution in the turbine disk.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166411000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-2853","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354474","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"石川島播磨重工"},{"subitem_text_value":"石川島播磨重工"},{"subitem_text_value":"早稲田大学"},{"subitem_text_value":"早稲田大学"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"八田, 博志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"向後, 保雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"棚次, 亘弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大鍋, 寿一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"水谷, 智昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川田, 宏之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"重村, 卓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HATTA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOGO, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TANATSUGU, Nobuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OHNABE, Hisaichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIZUTANI, Tomoaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWADA, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHIGEMURA, Takashi","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0166411.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166411.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32738/files/SA0166411.pdf"},"version_id":"a4bee83e-1f25-4439-aad2-e8c98ed49315"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ATREX 用 C/C 複合材料製タービンディスクの概念設計","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ATREX 用 C/C 複合材料製タービンディスクの概念設計"}]},"item_type_id":"9","owner":"1","path":["1890","1911"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32738","relation_version_is_last":true,"title":["ATREX 用 C/C 複合材料製タービンディスクの概念設計"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:25:24.974635+00:00"}
