Comprehensive Analysis of Frictional Properties, Wear, and Thermal Stability of Commercial Brake Pads and Evaluation Using Ranking Technique for Automotive Applications
摘要
This study evaluates the tribological performance of two aftermarket (AM) brake pads (BP-1 and BP-2) and one original equipment (OE) brake pad (BP-3) using a variety of tests including fade and recovery cycles, coefficient of friction (CoF) under different conditions, wear analysis, and thermal stability. BP-3 consistently outperformed the other samples, demonstrating superior thermal stability, wear resistance, and the highest CoF (0.518) under high-temperature conditions. It had the lowest fade percentage (5.88%) and the highest recovery (114.59%), making it the most reliable for high-temperature braking applications. BP-1 performed well with a good CoF (0.509) but exhibited higher fade (24.19%). BP-2 showed the lowest performance overall with low CoF, high wear, and inadequate fade resistance. The ranking based on the Extension Evaluation Method (EEM) placed BP-3 as the top performer, followed by BP-1, with BP-2 requiring significant improvements to meet safety standards. This research concludes that BP-3 is the most balanced and durable brake pad for consistent braking performance, making it a superior choice for extended use in vehicles.
