An Experimental Case Study on The Comparison of The Use of Micronized Quartz and Alumina in Brake Pads

One of the crucial components of the brake system is the brake pads. Due to its importance in the sector, researchers have carried out many recent studies on this subject. In this study, two different brake pad samples were developed from alumina material and micronized quartz material as friction modifiers. Samples containing 12% alumina and micronized quartz were produced by hot molding method. The friction coefficient and wear rates were established in the brake pad tester in order to assess the performance of the created brake pad samples. Density, hardness, and microscopic analyses of the samples, which are other important parameters, were performed with Scanning electron microscopy. The average coefficient of friction was 0.35 in samples containing micronized quartz and 0.34 in samples containing alumina. The wear rates in both samples were obtained below the maximum desired wear rate from the brake pads. The experiments produced brake pad performance values with the desired characteristics, and it was found that micronized quartz material may be employed as an alternative to alumina in the composition of brake pads.
