構造技術の研究:GXロケットLNG推進系複合材タンク開発支援のための評価試験 Researches on space structural technology: Cryogenic mechanical performance assessments for LNG composite tank development of the GX rocket He, Jianmei 下田, 孝幸 幸節, 雄二 He, Jianmei Shimoda, Takayuki Kosetsu, Yuji CFRP 複合材料 アルミニウム 燃料タンク 宇宙構造体 熱応力 熱膨張 破壊強度 CFRP composite material aluminum propellant tank space structure thermal stress thermal expansion fracture strength Adhesively-bonded structure between CFRP composites and Aluminum metal (Al) plays an important role in the development of a light-weight Aluminum-lined CFRP cryogenic propellant tank in terms of design safety and durability. Large thermal stresses and strains produced by the difference of thermal expansion ratios among an adhesive material, CFRP composite and aluminum liner will lead to the potential of fracture strength deterioration for CFRP-Adhesive-Al bond structures at cryogenic temperatures below - 150 C. In this study, experimentally investigated was some temperature-dependent mechanical performance of the adhesive film AF163-2K itself and CFRP-AF163-2K-Al bond structures. 資料番号: AA0047944008 レポート番号: JAXA-RM-04-009 宇宙航空研究開発機構 Japan Aerospace Exploration Agency (JAXA) 2004-10-29 jpn technical report https://jaxa.repo.nii.ac.jp/records/2739 1349-1121 AA11983593 宇宙航空研究開発機構研究開発資料: 平成15年度総合技術研究本部宇宙領域研究成果報告書:輸送系 JAXA Research and Development Memorandum: FY15 Annual Report of Research & Development on Space Technology in the Institute of Space Technology and Aeronautics: Space Transportation System JAXA-RM-04-009 37 42 https://jaxa.repo.nii.ac.jp/record/2739/files/47944008.pdf application/pdf 1.3 MB 2020-01-15
