신에너지 수송용 차량의 하이브리드 복합소재 차체에 대한 최적 제작 프로세스 연구

Abstract

The following result was found through this study. Although use of an all-composite structure a transportation vehicle may have higher manufacturing cost than other material structures, if a social economic framework, that both the life cycle cost including the operational phase cost and the environmental impact would be more important parameters, is considered the all-composite structure becomes clearly the best solution for economic point of view relatively to other material structures such as the metal structure or the hybrid metal-composite structure. This study was an objectification to the interrelation equation to fuel costs, maintenance costs and pollutant emission costs about light weight composite carbody and evaluated the break-even-point according to all-composite carbody manufacture cost rise about existing metal vehicle. And this study treated the carbody requirement performance and considered a reduction production cost according to the composite manufacture. Finally, all-composite structure evaluated most efficient in an operation energy side.
