Many parts for transmitting power are incorporated in an automatic transmission of an automobile. The technical problems of the wet clutch disc (DISC) having important functions related to gear shifting are to improve the automatic gear shifting performance and to ensure the stability of the power transmission torque in the contact action between the DISCs. DISC is manufactured by adhesive bonding of friction material (Fa) and iron core plate (C/P). In particular, the stabilization of the DISC

In this study, the robustness of the DISC bonding sizing method by applying robust design was aimed at stabilizing the bonding strength and thickness accuracy, and the optimum processing conditions were extracted to optimize the mass production method.
