Three point bending tests and tensile tests were carried out for two kinds of carbon/epoxy composites, and the Weibull statistics based on weakest link theory was applied for evaluating the size effect. The size effect was calculated as a function of the effective volume, surface area, or edge length using the Weibull parameters obtained from three point bending tests, and the numerical results were compared with the experimental results. As a result, it was found that competing risk model considering both effective volume and surface area showed good agreement with the experimental results. It was demonstrated that the transverse tensile strengths of unidirectional carbon/epoxy composites are basically equivalent to the bending strengths.","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_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064233000","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-08-007","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材料グループ"},{"subitem_text_value":"航空宇宙技術振興財団"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Advanced Materials Group, Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Foundation for Promotion of Japanese Aerospace Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小笠原, 俊夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"原, 栄一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ogasawara, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hara, Eiichi","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":"64233000.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64233000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2599/files/64233000.pdf"},"version_id":"3ff17698-430a-463e-87de-465900021a09"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Transverse tensile strength, Size effect, Weibull statistics, Unidirectional composite laminate","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":"一方向炭素繊維/エポキシ複合材料の90°引張り強度における寸法効果について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"一方向炭素繊維/エポキシ複合材料の90°引張り強度における寸法効果について"}]},"item_type_id":"3","owner":"1","path":["1253","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"2599","relation_version_is_last":true,"title":["一方向炭素繊維/エポキシ複合材料の90°引張り強度における寸法効果について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:19:20.697765+00:00"}
