Friction plate, one of key elements for torque transfer in lock-up clutch system, is made of wet friction material by synthetic fiber. Drag torque by these friction plates affects hydraulic performance of torque converter. This study showed the relationship between drag torque and hydrodynamic performance of torque converter with different number of friction plates at various ATF(Automatic Transmission Fluid) temperatures and rotation speeds.
