摘要/Abstract

摘要： 以自润滑材料和摩擦材料为例，基于非平衡热力学原理从热量产生和传递的根本问题出发，研究摩擦系数和热导率对材料接触面温度的影响，指导聚合物基复合材料的设计。对于自润滑材料来说，将摩擦热量产生和传递过程假设成两个过程的串联，发现摩擦热产生是摩擦系统整体稳定运行的关键控制因素。对于摩擦材料来说，将摩擦热量传递过程假设成传递热量和分配热量两个过程的并联，发现需采用降低刹车片热导率的逆向思维降低接触面温度。

Abstract: 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.

Key words: thermodynamics, composites, self-lubricating materials, friction materials, friction heat generation, heat transfer
