Non-equilibrium thermodynamics analysis and its application for polymer composites design in tribological fields

• The heat generation and transfer process of self-lubricating materials and friction materials was quantitatively described from the fundamental principle of non-equilibrium thermodynamics. The effect of friction coefficient and thermal conductivity on the contact temperature of materials was studied, and the finding could guide the design of polymer composites. For the self-lubricating materials, the frictional heat generation and transfer process was assumed to be two processes in series. The frictional heat generated was the key controlling factor for stable operation of the friction system. For the friction materials, frictional heat transfer process was assumed to be heat transfer and heat distribution, two processes in parallel, and it was required to reduce thermal conductivity of the brake pads in order to lower contact surface temperature.
