Abstract
The mechanical performance of the brake shoe liners dictates the safety and efficiency of the vehicles; thus, brakes are very vital in ensuring controlled deceleration and stopping. In the past few decades, composites have significantly impacted the automotive industry through lighter, stronger, and sturdier alternatives to traditional materials improving overall performance. Nano additives are of key importance in such composites, improving not only the mechanical properties but, more significantly, the tribological ones when used in wear strength-stress conditions. This research paper addresses the mechanical and tribological properties of natural fiber brake shoe liner material, such as banana and coir, used as a base material for the composite. Besides, nano additives like aluminum oxide (Al₂O₃) and silicon carbide (SiC) are added to 10% weight ratio in composite samples for further improvement in the properties of these natural fiber composites. The nanomaterials, added to the brake lining, will improve the hardness, wear resistance, and thermal stability of such materials. These are factors to be considered in determining its service life and ensuring that the automotive brake system is reliable. The experimental results give the comparative analysis of the mechanical properties that are tensile strength, hardness, and wear resistance between the base composite and the nano-reinforced composite. Sample 4 and Sample 5 performed better when compared to other specimens. The wear rate of these specimen increases slowly as the distance increases. The COF obtained was 0.4 which is equal to COF of semi-metallic brake liner. Both Sic and Al2O3 provide same range COF. But Al2O3 provides less wear rate in long run. The test results present that the addition of Al₂O₃ and SiC significantly enhance the brake liners’ performance.
Keywords: Banana fibre, coir fibre, Al2O3, SiC, epoxy resin, tensile test, flexural test, wear test, water absorption test, compression test.
