The paper-based friction pairs are widely used in the multidisc wet clutches in the transmission system of commercial and civil cars.
Paper-based friction material has a porous microstructure, enabling the lubricant to reach the contact interface and providing lubrication. As power shift and torque transfer devices, wet clutches frequently work under extremely challenging conditions, including high initial relative sliding velocity, high surface pressure, and high temperature rise. It is essential to investigate the frictional performance of friction pairs to optimize the design of wet clutches and improve vehicle performance.
