Effect on the Properties of Brake Pads of Recycling Dust as Filler

Abstract

This research is focused on the effect 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, the proper type of recycling dust reused in brake pad formula was investigated by changing recycling dust type in mixing process. In the experiment, the properties of brake pads, hardness, density, porosity, and Young’s modulus were measured. Furthermore, the morphology and composition of recycling dust will be characterized by X-Ray Fluorescence (XRF), and Scanning Electron Microscopy (SEM). The developed composite brake pad showed that the value of density and compressibility increased while the value of hardness and Young’s modulus decreased by adding 10wt% of recycling dust to commercial brake pad formulation. Hence, the benefit of this work is using recycling dust as one of alternative fillers in disc brake pad materials without compromising the quality and performance.
