자동차 차체 경량화를 위한 알루미늄 5182-폴리프로필렌 샌드위치 판재의 상용화 기술 개발
An aluminium sandwich sheet is the composite adhered by rolling two aluminum panels to one plastic core. If it has the same bending stiffness as an steel sheets, it is about 65% lighter than steel sheet and 30% lighter than aluminum sheet. In present study, we intend to develop application technologies of an aluminum sandwich sheet for auto body panels from selecting composed materials of aluminium sandwich sheets to fabricating prototype. For this study, for the application of a light sandwich sheet to an automotive hood part, ribbing process so called, hemming for which joined between an inner and an outer panel was introduced. From these results, it was found that the sandwich sheet could improve the weight and maintain the flexural rigidity simultaneously comparing to the steel sheet.
