ABSTRACT In this research, high quality asbestos free brake pads were produced from Banana Pseudo-Stem Fibre (BSF) and Sugarcane-Bagasse particles (BP) as reinforcement material and fillers respectively, epoxy resin as binder material, graphite as lubricant and Iron Oxide as the abrasives. A commercial brake pad was used as control sample of these constituent. Five different samples were produced by varying compositions based on loading levels, 2%, 4%, 24%, 27%, 30%, and 40% by weight of Banana Pseudo Stem and Sugarcane (Bagasse) to matrix. The Binder, lubricant and abrasive composition were kept constant. The method of production used in the work was the simple hand lay-up technique which was followed by hot compression allowing for post-production curing. The physical, mechanical, thermal, morphology and tribological properties of the composite were investigated to obtain the density, water absorption, tensile strength, flexural strength, macrostructural, thermal stability, hardness, friction and wear rate in order to determine the optimum composition. The experiments showed that the best sample was S22 with 27% wt of BSF as reinforcement, 27% wt of BP as filler, 40% wt of Epoxy as binder, 4% wt of Iron oxide as abrasive and 2% wt. of graphite as lubricant and result was compared with control sample. Sample S22 competed comparatively with the commercial brake pad. The optimized sample S22 has hardness property of 7.3HRF, tensile strength of 17.32N/mm2, Flexural Strength of 36.80N/mm2, it has a decomposition temperature of 300oC, Coefficient of friction of 0.1400, wear rate of 0.0045mg/sec, water absorption (%) of 24.21 and a density of 1.36g/cm3. The properties of control samples are hardness property of 7.7HRF, Flexural Strength of 23.3N/mm2, it has a decomposition temperature of 200oC, Coefficient of friction of 0.288, wear rate of 0.1727mg/sec, and a density of 2.70g/cm3. The properties obtained compared favorably with the workable commercial brake pads. The brake pad was produced using the optimum formulation. |
