Tensile tests of bolted joint specimens with stainless steel bolts were carried out at room temperature. The screw size was M6×1, M8×1.25, and M10×1.5, and the screw depth was in range of 6-12 mm. Both a directly threaded hole and a coil thread insert hole were evaluated. As results, the tensile strength of threaded hole was almost identical to the estimated values using the out-of-plane shear strength of the CFRP. The joint separation load was calculated using a conventional bolted joint theory, and the best fit coefficient of friction was 0.19. No residual deformation was observed under tension-tension cyclic load when the maximum load was lower than the separation load. This result suggests that the joint may be applicable under the loading condition.","subitem_description_type":"Other"}]},"item_3_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_3_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_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064965000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RM-11-002","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1121","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11983593","subitem_source_identifier_type":"NCID"}]},"item_3_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本部複合材グループ"},{"subitem_text_value":"宇宙航空研究開発機構研究開発本部複合材グループ"},{"subitem_text_value":"宇宙航空研究開発機構宇宙輸送ミッション本部宇宙輸送系要素技術研究開発センター"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Advanced Composite Group, Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Advanced Composite Group, Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Space Transportation Subsystem Research and Development Center, Space Transportation Mission Directorate, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小笠原, 俊夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉村, 彰記"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"紙田, 徹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ogasawara, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshimura, Akinori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kamita, Toru","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":"2020-01-15"}],"displaytype":"detail","filename":"64965000.pdf","filesize":[{"value":"667.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64965000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2553/files/64965000.pdf"},"version_id":"1d205528-1b60-41a2-afe6-a365ebe971db"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bolted joint","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tensile strength","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Threaded screw hole","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon fiber composites","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"平織CFRP積層板に加工されたネジ穴の引張り強さ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"平織CFRP積層板に加工されたネジ穴の引張り強さ"}]},"item_type_id":"3","owner":"1","path":["1208","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"2553","relation_version_is_last":true,"title":["平織CFRP積層板に加工されたネジ穴の引張り強さ"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:20:13.055436+00:00"}
