Abstract: Production of composite brake linings; mixing, cold and hot pressing (molding) and heat treatment steps. The aim of this study is to investigate the effect of hot-pressing pressure on friction performance in the production of composite brake linings. As the pressure applied during the hot-pressing step increases, the density of the product increases as the gap between the materials forming the product decreases. Therefore, the pressing pressure, which is one of the production parameters, is very important for the friction performance of composite brake lining materials. In this study, composite brake lining samples having the same content were produced by applying three different hot-pressing pressures such as 8000, 13000, 18000 kPa and friction performances were examined. The friction coefficients of the samples with 13000 and 18000 kPa pressing pressure were low. The most suitable pressing pressure was determined as 8000 kPa.
