Comparative Study on the Tribological Performance of Conventional and Metal Matrix Composite Brake Pads in Automotive Applications

This study investigates the wear and mechanical properties of aluminum alloy composites reinforced with titanium dioxide (TiO2) nanoparticles. Aluminum-based composites are increasingly favored in engineering due to their excellent properties, and incorporating TiO2 nanoparticles presents a promising method for further enhancement. The composites were produced using a powder metallurgy technique, and their mechanical performance—including tensile strength, hardness, and impact resistance—was thoroughly assessed. Additionally, wear tests under various conditions were conducted to evaluate the composites' wear resistance. The findings indicate that incorporating TiO2 nanoparticles significantly enhances both the mechanical properties and wear resistance of the aluminum alloy.
