The SiC fiber containing 10 mass% oxygen was silanized by two methods, using experimental silane coupling agents containing 0.5, 1.0, and 2.0 mass% 3-(Methacryloyloxy) Propyl Trimethoxy Silane (γ-MPTS). The silanization methods were the drying method, which enabled silanization at atmospheric conditions for two weeks, and the heating method, which enabled silanization at 100°C for 30 min. After silanization, SiC fibers were analyzed by Fourier Transform Infrared (FTIR) spectroscopy. Mechanical properties of experimental SiC fiber-reinforced resin were measured by the three-point bending test according to ISO 4049:2009, and the fracture surface of SiC fiber-reinforced resin was observed using an Electron Probe Micro Analyzer (EPMA).\nResults: The FTIR absorbance peaks at 815 cm-1 attributed to the Si-O-CH_3 groups of the γ-MPTS and 1087 cm^-1 attributed to the Si-O-Si siloxane bonding were observed on the SiC fiber silanized with 1.0 mass% γ-MPTS by the drying method. Moreover, EPMA observation showed that these SiC fibers were covered with the matrix resin. Thus, these SiC fibers could adhere chemically to the matrix resin. The flexural strength and modulus of the fiberreinforced resin containing the SiC fiber silanized with 1.0 mass% γ-MPTS using the drying method were 238.7 ± 41.1 MPa and 6.0 ± 1.1 GPa, respectively. In contrast, those of the SiC fiber-reinforced resin containing the SiC fibers silanized by the heating method was not improved.\nConclusion: The reinforced resin containing the SiC fiber silanized with 1.0 mass% γ-MPTS by the drying method showed mechanical properties superior to those of the other SiC fiber-reinforced resin.","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"学位の種類: 博士（歯学）. 報告番号: 甲第4590号. 学位記番号: 新大院博（歯）甲第439号. 学位授与年月日: 平成31年3月25日","subitem_description_type":"Other"},{"subitem_description":"Dentistry. 2018, 8(11), 524","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博（歯）甲第439号","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"13101甲第4590号"}]},"item_6_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"175259","nameIdentifierScheme":"WEKO"}],"names":[{"name":"髙, 昇将"}]}]},"item_6_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学"}]},"item_6_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.4172/2161-1122.1000524","subitem_relation_type_select":"DOI"}}]},"item_6_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"【○!C】 2018 Norimasa T, et al."}]},"item_6_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"ETD"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Taka, Norimasa"}],"nameIdentifiers":[{"nameIdentifier":"175258","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-09-10"}],"displaytype":"detail","filename":"h30ndk439.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://niigata-u.repo.nii.ac.jp/record/32125/files/h30ndk439.pdf"},"version_id":"c9f21072-902c-4869-8379-63fd50a5c0fa"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-09-10"}],"displaytype":"detail","filename":"h30ndk439_a.pdf","filesize":[{"value":"290.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","url":"https://niigata-u.repo.nii.ac.jp/record/32125/files/h30ndk439_a.pdf"},"version_id":"5950e378-e2d7-480a-a47e-56ed08c2fd57"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SiC fiber","subitem_subject_scheme":"Other"},{"subitem_subject":"Fiber-reinforced resin","subitem_subject_scheme":"Other"},{"subitem_subject":"Silanization","subitem_subject_scheme":"Other"},{"subitem_subject":"Flexural properties","subitem_subject_scheme":"Other"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Effects of Silanization Conditions on Flexural Properties of Sic Fiber-Reinforced Resin","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of Silanization Conditions on Flexural Properties of Sic Fiber-Reinforced Resin"},{"subitem_title":"Effects of Silanization Conditions on Flexural Properties of Sic Fiber-Reinforced Resin","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["455","434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-07-09"},"publish_date":"2019-07-09","publish_status":"0","recid":"32125","relation_version_is_last":true,"title":["Effects of Silanization Conditions on Flexural Properties of Sic Fiber-Reinforced Resin"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T04:02:29.273478+00:00"}
