Investigation of Mechanical Properties and Performance of Automotive Brake Pads

In this work, three composite formulations BP1, BP2, and BP3 are developed and tested in order to examine the wear characteristics of automotive brake pads. Each composite uses powder metallurgy to combine performance optimized materials, such as graphite, and powdered materials as suitable reinforcements. Under various pressure conditions, the brake pad samples' wear rate, hardness, braking force, noise, vibration, and coefficient of friction were all examined. Particularly at high pressures, BP1 showed greater braking force and frictional effectiveness; however, this came at the expense of increased wear and noise. With moderate noise, vibration, and wear resistance, BP2 provided a well-balanced characteristic. While having less friction and braking force, BP3 demonstrated the lowest wear rate and the least amount of noise, which makes it a good choice for applications that value longevity and quieter operation. According to the results, choosing the best brake pad composition relies on the particular performance needs, with BP1 being best suited for high-force applications and BP3 with a longer lifetime and less noise.
