Production of Vehicle Brake Lining with Andesite Powder Additives at Different Pressing Pressures and Determination of Their Effects on Braking Performance

Öz

The purpose of braking systems is to stop or slow down the moving vehicle. Braking is achieved by converting kinetic energy into heat energy due to the friction created by the brake pads. Today, it is common to use disc brake systems on both front and rear wheels. Recently, serious studies have been carried out in different sectors to utilize industrial wastes, and it is aimed at bringing these waste products into the economy. For this purpose, using different materials in the brake pad contents is common. This study aims to utilize the waste powders resulting from the processing of andesite stone. The materials used in the brake pad samples were developed by the hot-pressing method at pressing pressures of 15, 20, 25, 30, 35, and 40 MPa. Friction coefficient, wear rate, density, hardness, and SEM analysis of the samples were performed. As a result of the study, the density and hardness of the lining samples increased with the increase in pressing pressure. The maximum friction coefficient was obtained in the 40 MPa sample, and the minimum wear rate was obtained in the 25 MPa sample. It was determined that the coefficient of friction and wear rate performances of the lining samples meet the desired properties for the lining. Using andesite dust waste material in the brake lining sector will contribute to the environment and economy.
