Evaluation of the influence of the main components of the friction layer of brake pads on the coefficient of friction, wear and thermal characteristics in the friction zone
Abstract
Increasing road safety requirements, along with the growing thermal and mechanical loads on braking system components, highlight the need for an in-depth study of the friction and wear processes of brake pads. The composition of the friction layer plays a decisive role in determining the friction coefficient, the stability of operational characteristics, and the wear intensity, particularly under elevated temperatures and variable loading conditions. The aim of this study is to analyze the influence of various components of the brake pad friction layer on their tribological and thermal properties, as well as to establish scientific foundations for optimizing material composition in terms of braking efficiency, durability, and thermal resistance. The work focuses on identifying the regularities governing changes in the friction coefficient, wear, and thermal processes in the contact zone when using different types of friction materials.
