Dupont in February 1972 as a reinforcement for composites, which has a tensile strength similar to carbon fibers. KEVLAR-49 composite consists of matrices of epoxy(Epon 828). Static mechanical tests included determination of tensile and flexural strength, Young’s modulus, interlaminar shear strength and Poisson’s ratio. Poisson’s ratio was determined by using the laser holography method and the strain gage method. The repeated flexural fatigue property was determined by using the NAL type fatigue tester of a constant load type. KEVLAR-49 composites have lower flexural strength than carbon fiber composites. In order to improve this property we developed a hybrid of KEVLAR-49 and carbon fiber composite and found that the hybrid has sufficient flexural and fatigue strength for use as structural material.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0413000","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: NAL TR-413","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所機体第一部"},{"subitem_text_value":"航空宇宙技術研究所機体第一部"},{"subitem_text_value":"航空宇宙技術研究所機体第一部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"First Airframe Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"First Airframe Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"First Airframe Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古田, 敏康"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野口, 義男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松嶋, 正道"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"FURUTA, Toshiyasu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NOGUCHI, Yoshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUSHIMA, Masamichi","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr00413.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00413.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44662/files/naltr00413.pdf"},"version_id":"494a0277-8900-42f6-a355-4c25ea7be425"}]},"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":"KEVLAR-49複合材の強度と曲げ疲労強度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"KEVLAR-49複合材の強度と曲げ疲労強度"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44662","relation_version_is_last":true,"title":["KEVLAR-49複合材の強度と曲げ疲労強度"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:53:03.722019+00:00"}
