Abstract
This research investigates the effect of different abrasives (red mud, steel slag, and flyash) on the tribological characteristics of non-asbestos brake friction materials. Three distinct brake friction composites were produced by changing the proportions of essential components such as red mud, steel slag, and fly ash while maintaining the proportions of other parental ingredients. Consequently, friction composites with different abrasives were developed and evaluated for mechanical, chemical, and physical properties as per industrial standards. Using the Chase friction test equipment, the tribological characteristics were determined experimentally in line with IS2742 part-4. The experimental results indicate that fly ash particles in friction composites exhibited consistent fade and recovery behaviours with a lower wear rate. In comparison, steel slag based friction composites exhibited a better recovery behaviour. SEM analysis showed plateau development, pits, fractures, and various other features on the surface of the examined brake pads.
