Tensile Tests were conducted on four types of specimens (unidirectional, 0°/90°ply, boron fibre and shear lag test pieces). The results show that the A.E. Characteristics (count rate, amplitude distribution and location) differ with the failure mode. The A.E. amplitude was above 90 dB for the fibre breakage of the unidirectional ply test piece but below 90 dB for the transverse one of cross ply, which fractured at a low level load, while the shear lag test pieces produce and acoustic emission amplitude in the range of 40～60dB under delamination fracture mode.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0927000","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-927","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原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"祖父江, 靖"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小河, 昭紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SOFUE, Yasushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OGAWA, Akinori","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":"naltr00927.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00927.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45186/files/naltr00927.pdf"},"version_id":"5e457cd3-a586-4c27-a907-31afff1534de"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Fracture Mode Research of Boron Aluminum Composite Materials by Acoustic Emission (AE)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fracture Mode Research of Boron Aluminum Composite Materials by Acoustic Emission (AE)","subitem_title_language":"en"}]},"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":"45186","relation_version_is_last":true,"title":["Fracture Mode Research of Boron Aluminum Composite Materials by Acoustic Emission (AE)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:43:47.190194+00:00"}
