틸팅열차(TTX) 차체 구조용 샌드위치 복합소재의 단열 특성평가
오경원(Kyung-won Oh),이상진(Sang-jin Lee),정종철(Jong-choel Jeong),김정석(Jeong-seok Kim),조세현(Se-Hyun Cho) 대한기계학회 2005 대한기계학회 춘추학술대회 Vol.2005 No.11
Experimental investigations on heat transportation ratio were firstly performed with three types of sandwich panels such as the Carbon/Epoxy Skin-Aluminum Honeycomb and Balsa Core Sandwich Panel of 37㎜ thickness, the Carbon/Epoxy Aluminum Skin-Honeycomb Core Sandwich Panel of 57㎜ thickness (including insulator) and the Carbon/Epoxy Skin-Aluminum Honeycomb Core Sandwich Panel of 37㎜ thickness based on the KS F 2278:2003(Insulation test method of windows). In additional to this investigation, experimental tests were also done for evaluation of heat transportation ratio with the Aluminum Skin- Aluminium Honeycomb Sandwich Panels of 27㎜ and 35㎜ thickness, and Aluminum Skin-Foaming Aluminum Sandwich Panel of 27㎜ thickness by the KS F2277:2002(Insulation measuring method of construction component - Calibration heat box method or protective heat box method). In this study, it was found that the larger net heat transfer cross sectional area between the skin and the sandwich core is given, the higher heat transportation ratio occurs. And the hybrid type insulation had better insulation characteristics compared to the non-hybrid type insulation.
