Abstract

Abstract: Copper is an outstanding ingredient of friction materials (FMs) due to its multi-functional performance. Despite all its various positive contributions in FMs, it has been recently reported as a hazard for an aquatic life and has become a focus of concern for the FM Industry. Hence in the current work, group of novel ingredients was explored for Cu-replacement. Some conducting ingredients were added to compensate the conductivity of Cu. One more novel ingredient Promaxon-D was used as a theme ingredient. The developed pads (metal-free) were characterized for tribological properties on the inertia dynamometer as per JASO-C-406 standards. It was concluded that Promaxon-D proved successful in Cu-replacement almost in all respects barring wear. With increase in an amount of Promaxon-D, most of the properties got improved. Highlights: Successful efforts were made to replace Cu (environmental pollutant) in the brake-pads. Metal-free brake-pads were developed to compete with Cu containing pads. Hydrated calcium silicate (Promaxon D) proved successful to replace Cu. Promaxon D outperformed all performance properties except wear. Higher the amount (0, 5, 10 wt%), more were the benefits.
