Abstract

In this study, structural design and analysis of the automobile bonnet is performed. The flax/vinly ester composite material is applied for structural design. The Vacuum Assisted Resin Transfer Molding-Light (VARTML) manufacturing method is adopted for manufacturing the flax fiber composite bonnet. The VARTML is a manufacturing process that the resin is injected into the fly layered-up fibers enclosed by a rigid mold tool under vacuum. A series of flax/vinyl ester composite panels are manufactured, and several kinds of specimens cut out from the panels are tested to obtain mechanical performance data. Based on this, structural design of the automobile bonnet is performed.

본 연구에서는 차량용 본넷의 구조 설계 및 해석을 수행하였다. 구조 설계를 위해 아마/비닐 에스테르 복합재료가 적용되었다. 아마 섬유 복합재 본넷의 제조공법은 VARTML(Vacuum Assisted Resin Transfer Molding-Light) 제조공법이 적용하였다. VARTML 공법은 한쪽 면은 견고한 금형을 사용하고 다른 면은 진공과 함께 유연한 금형을 사용하여 압력차를 이용하여 내부에 적층된 섬유에 수지를 신속하게 함침 시켜 성형하는 방법이다. 아마/비닐 에스테르 패널로 부터 시편을 가공하여 재료의 기계적 물성치를 획득하기 위한 시편 시험을 수행하였다. 이를 기반으로 자동차 본넷의 구조 설계를 수행하였다.
