Investigation of Tribological Properties of Brake Friction Materials Developed from Industrial Waste Products

Abstract

Various international initiatives on environmental issues and the need to protect the environment are promoting the use of industrial waste in a variety of applications, including automotive brake pads. These studies show that the reuse of industrial waste can help to reduce the environmental impact. The development of environmentally friendly and cost-effective composites for use in a variety of engineering applications is the need of the century. The use of industrial waste in composite production is a possible solution for both problems. In this study, the potential use of talc, quartz and ceramic waste FFC fracture as a friction modifier in brake friction materials and its performance properties in accordance with industry requirements were investigated. The tribological, physical and mechanical properties of the brake pads were measured, and the friction surface morphology was investigated by scanning electron microscopy. According to the results obtained, the highest specific wear rate was observed in the FM3 sample. The FM2 sample with the highest hardness and average friction coefficient showed the lowest wear. FM4, FM5 and FM6 samples with high talc and quartz content exhibited low coefficient of friction characteristics compared to other samples.
