Friction plate which is main torque transfer element in lock-up clutch system is made of wet friction material that is consisted of synthetic fiber. Factors that decide characteristics of friction material are material composition, surface of steel plate, ATF oil and control condition. Particularly, ATF volume capacity is a important factor for friction characteristics and durability of friction material. The analysis of friction and wear characteristics of friction plate is investigated by using LVFA machine. This study provides applicable ATF Volume capacity for lock-up clutch system.
