Effects of Recycling Dust as Filler in Disc Brake Pad on Brake Performance 2019-01-1423

This research is focused on the effect of particle size and proportion of Recycling Dust (RD) on properties and performance of brake pad composites. Recycling Dust was produced from grinding process of in-finishing products to standard thickness and was used as a new friction material in brake pads. Based on a simple experimental formulation, three different particle sizes were considered. Then, the proper amount of Recycling Dust reused in brake pad formula was investigated by changing the proportion of barite and Recycling Dust. In the experiment, the coefficient of friction and the specific wear rate were examined with brake dynamometer and constant friction speed. The properties of brake pad, hardness, density, and porosity, were measured. Furthermore, the morphology and composition of Recycling Dust will be characterized by X-Ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), acetone extraction and ash content techniques. The benefit of this work can be using recycling dust as one of alternative fillers in disc brake pad materials without compromising the quality and performance.
