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.
