Advanced Control of Frictional Properties on Paper Clutch Materials by a Combination of Friction Modifiers

This study proposes a novel approach for controlling frictional performances at paper clutch systems by a combination of organic friction modifiers (OFMs). The OFMs are commonly used for modifying the frictional properties at the paper clutch. Although the effect of the OFMs tends to be dependent on...
