To enhance frictional performance, wear and to obtain improved thermal stability with a reduction of noise, vibration, and harshness (NVH) and provide environment friendly brakes for the increasing needs of the population's comfort and safety requirements this study was initiated. The thermal stability of two different phenolic resins as binder on the frictional performance of brake composite material was studied. The two phenolic resins used are Durite phenolic resin and Bakelite phenolic resins. They were tested for friction, wear, thermal stability and degradation. This was executed by using a universal friction tester (UFT) for testing friction and wear, then on thermo gravimetric analysis (TGA) and the TGA results indicate more mass loss of NB samples contrary to test results. When individual materials were heated, Bakelite lost less mass compared to Durite. The friction test indicates more friction when used the NB samples but they had less wear and more stability nevertheless this could vary for other compositions and conditions.
