Abstract
In this paper, we investigated the application method and properties of 0.1 mm, 0.2 mm and 0.3 mm beads, which can secure a certain thickness due to the molding stability of joint surfaces of different materials (aluminum and composite). In order to verify this, the influence was evaluated according to the thickness of the adhesive in the Double lap test and the FEM simulation. As a result, it was confirmed that as the content of the bead of the adhesive increased more than 1%, the strength of the adhesion increased and the elongation decreased. We confirmed as the size of the bead became larger, the rigidity became lower and the elongation increased.

본 논문에서는 알루미늄과 복합재료에 대한 이종소재 접합면의 성형안전성을 위해 일정한 두께를 확보 할 수 있는 0.1 mm, 0.2 mm, 0.3 mm bead의 적용 방법과 물성변화에 대해 연구하였고, 이를 검증하기 위해 더블랩 시험과 FEM 시뮬레이션으로 접착제의 두께에 따라 미치는 영향을 평가하였다. 그 결과, 접착제에 bead의 양을 1% 이상 함량이 증가함에 따라 접착 소재의 강도가 높아지고 신율이 감소함을 확인하였고, bead의 크기가 커질수록, 강 성은 낮아지고, 신율은 증가함을 확인하였다.
