The friction materials are generally consisted of homogeneous dispersed friction materials in a metallic based which produced via a process of compaction and sintering of metallic powders, hard materials, and if necessary lubricant. The role of these materials in the components is transferring kinetic energy to heat and generating torque (brakes and clutches). This research is a property investigation of effected parameters in manufacturing of bronze based friction materials which is used in heavy automotive clutch plates, helicopter brakes, and etc. Four compositions were selected for bronze friction materials and different parameters such as compaction pressure, sintering time and temperature on density, porosity, and hardness were studied. The nearest results to imported samples are: compaction pressure of 5 t/cm2, sintering time and temperature of 30 min. and 820 DC respectively. The wear resistant in [mal sample containing 2% of hardened additives was determined by ASTM G-I05 standard and compared with foreign samples. The sample containing WC had the closest property and microstructure with imported samples.
