Abstract

Abstract: In order to make clear the engagement behavior, the numerical research is conducted to explore the influence of interface pressure on the tribological properties of carbon fabric reinforced phenolic composites. It is found that the dynamic friction torque is a linear function of interface pressure by curve fitting. And then the coefficient of dynamic friction is derived as an inverse proportional function of interface pressure. To demonstrate the results, the contact model is presented based on Gaussian surface asperity height distribution and the assumption of elastic deformation. Meanwhile, the asperity contact area is considered as the critical factor. Graphical abstract: Highlights: The dynamic friction torque is modeled as a linear function of interface pressure. Gaussian surface asperity height distribution is used. The μ d is investigated as an inverse proportional function of interface pressure. The contact model of rough surface is presented. The asperity contact area is critical for the dynamic friction torque.
