With N₂ as the carrier gas, however, no carbon fiber is observed. By this method, if the partial pressure of hydrocarbon, the amount of carrier gas and the time period for thermal decomposition are properly chosen, a large amount of carbon fibers of the diameter ranging from 7 μ to 100 μ and of the length reaching 25 cm can be obtained. Electron diffraction examination, optical microscope observation and resistivity measurement confirmed that the fibers thus obtained are polycrystalline and are composed of graphite layers parallel to the fiber axis. The tensile strength of the carbon fiber is about 20 ton/cm² to the fiber of the diameter 7μ","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 28: 45-54 (1970)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小山,  恒夫","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering28-05.pdf","filesize":[{"value":"786.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering28-05.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13028/files/Engineering28-05.pdf"},"version_id":"c5088b22-06c5-4832-815d-2acf86d2acc6"}]},"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":"気相成長式炭素繊維","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"気相成長式炭素繊維","subitem_title_language":"ja"},{"subitem_title":"Carbon Fibers Obtained by Thermal Decomposition of Vaporized Hydrocarbon","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1279"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-03-30"},"publish_date":"2009-03-30","publish_status":"0","recid":"13028","relation_version_is_last":true,"title":["気相成長式炭素繊維"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T04:43:03.929291+00:00"}
