Development and Tribological Evaluation of Advanced Composite Brake Materials for High-Speed Automotive Applications

Abstract

The increasing demand for high-speed automotive systems has intensified the need for advanced brake materials capable of providing superior frictional performance, thermal stability, and wear resistance under extreme operating conditions. Conventional brake materials often experience limitations such as excessive wear, thermal degradation, brake fade, and reduced durability during high-speed braking operations, affecting vehicle safety and braking efficiency. This research presents the development and tribological evaluation of advanced composite brake materials for high-speed automotive applications to enhance braking performance, durability, and thermal resistance. The proposed study investigates the fabrication of composite brake materials using advanced reinforcement constituents, ceramic additives, metallic fillers, and polymer-based matrices to achieve improved frictional and mechanical characteristics. Experimental analysis is conducted to evaluate the tribological behavior of the developed brake composites under varying load conditions, sliding velocities, and braking temperatures. Material characterization techniques are employed to examine microstructural features, surface morphology, wear mechanisms, and thermal degradation behavior. Performance evaluation is carried out using parameters such as coefficient of friction, wear rate, thermal stability, hardness, braking efficiency, fade resistance, and heat dissipation capability. Comparative analysis is further performed between conventional brake materials and the developed composite systems to determine improvements in tribological performance and operational reliability.
