In the previous study, corrugated metal gaskets using single material SUS 304 was developed. The corrugated metal gasket with elastic model for high surface roughness flange produce a leak due to only partial contact occurs. To increase the contact width between flange and gasket, surface layer in the both outside of gasket is required. The layer materials should softer than base material. In this study, Cu-SUS304-Cu laminated corrugated metal gasket is investigated by using computer simulation. Finite element software is used to observe contact width and contact stress on laminated corrugated metal gasket. The design parameter is pitch 1 (p1), pitch 2 (p2), pitch 3 (p3), thickness of base material (t), radius (R), height (h), and thickness of laminate (t2). Based on the helium leak data, the leakage performance of laminated corrugated metal gasket is better than previous corrugated metal gasket. The optimal design is selected by using slope of contact width and axial force curve. Taguchi method used to determine the optimum design by using L18 matrix. The optimal design of laminated corrugated metal gasket are p1 = 4.5 mm, p2 = 3.5 mm, p3 = 4 mm, t = 1.5 mm, R = 1,5 mm, h = 0.35 mm and t2 = 0.1 mm. © 2019 UTHM Publisher. All rights reserved.
