Abstract

The investigation of coal ash and palm Kernel shell for brake pad production is presented as follows, no change after 30mins of exposure to temperature of 240OC, 73.53%, water absorption and specific gravity of 0.756. The disc brake friction lining with the geometrical specification of Peugeot 504 model was produced using coal ash and palm Kernel shell as base materials, polyester resin as binder materials, fiber mesh as reinforcement, brass flex as abrasives and rubber dust from burnt tire as filler. The commercial brake pad gotten from the market was used as a control. Nine groups of sample were produced containing different percentage composition the materials. The samples were subjected to hardness, wear, specific gravity and oil/water absorption tests. Result showed 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 (Sample 5). 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.
