ABSTRACT
Brake pad is a friction device created by mix of different materials equipped for holding the braking properties. This paper presents optimization of design parameters for coal powder and palm kernel shell brake pad. The disc brake lining was delivered in accordance with the geometrical particular of Peugeot 504 model utilizing coal fiery remains and palm kernel shell as base materials. Polyester resin was utilized as restricting material, fiber mesh as fortification, brass flex as abrasives and elastic residue from consumed tire as filler. The business brake pad gotten from the market was utilized as a control. Nine gatherings of test were delivered containing diverse rate arrangement of the materials. The examples were exposed to hardness, wear, particular gravity and oil/water ingestion tests. Result demonstrated that hardness, thermal resistance and specific gravity increases with increase in coal ash content while wear rate reduces with increase of coal ash. Taguchi method of design of experiment was used to determine the optimum design mix and optimum design parameter. Wear rate and hardness were used as response with molding temperature curing time and heat treatment time as control factors. Results showed that the optimum setting for wear rate is 175oC molding temperature, 8mins curing time and 3hrs heat treatment time. For hardness the optimum settings is 175oC molding temperature, 6mins curing time and 3hrs heat treatment time. Analysis of variance (ANOVA) was used to confirm the experiment that the most significant factor for wear rate is heat treatment time while the most significant factor for hardness is the molding temperature as depicted in their signal to noise ratio using minitab 2017 soft ware. 1.0
