“…The hardness of the micronized quartz sample was higher than that of alumina. The hardness values are similar to the studies in the literature [32,33]. Although the average friction coefficient is close to one another, the sample containing micronized quartz has a friction coefficient of 0.35.…”

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.

“…This friction produces the force necessary to slow or stop the vehicle. Over the past 110 years, innovations in modern friction materials have played a significant role in improving the overall performance of automotive braking systems [5][6][7][8]. These innovations have led to advances in friction materials, including the development of new composite materials that provide better braking efficiency, less wear and better thermal conductivity.…”

In this study, a fixed automotive friction material content was determined and the mechani-cal and tribological effects of manufacturing parameters on friction materials were investigat-ed. Parameters; pre-forming time (1-3-5 min) and pre-forming pressure (8-10-12 MPa), hot pressing time (5-10-15 min) hot pressing pressure (8-10-12 MPa) and hot pressing temperature (125-150-175 °C), curing time (4-8-12 h) and curing temperature (120-150-180 °C) were de-termined. The friction test of the produced samples was carried out under 0.551 MPa pressure and 7 m/s rotation speed for 90 min. In addition, the average COF, friction stability, specific wear rate, density and hardness values of the samples were calculated. According to the results obtained, the average COF value increased as the pre-forming time and pressure increased. With the increase in hot pressing time, the tribological properties of friction materials improved. Although there was an increase in the average COF value with increasing hot pressing pressure and temperature, the specific wear rates increased in these parameters. The specific wear rate increased with the increase in curing time and temperature. The highest specific wear rate among all samples was obtained in the sample cured at 180 °C. Finally, it has been suggested that 3 min for pre-forming time, 12 MPa for pre-forming pressure; 15 min for hot pressing time, 12 MPa for hot pressing pressure, and 150°C for hot pressing temperature; and a curing time of 8 h and curing temperature of 150 °C may be sufficient.

“…Many BFMs have been produced to obtain the desired tribological properties [3]. The tribological performance of the produced friction composite is greatly influenced by the amount and type of components categorized as functional and inert filler, binder, reinforcing element, friction modifier, lubricant and abrasive [4][5][6][7][8]. The combination of behavior and mechanical properties, along with the formulation of friction materials, plays an important role in achieving the best performance.…”

Various international initiatives on environmental issues and the need to protect the environment are promoting the use of industrial waste in a variety of applications, including automotive brake pads. These studies show that the reuse of industrial waste can help to reduce the environmental impact. The development of environmentally friendly and cost-effective composites for use in a variety of engineering applications is the need of the century. The use of industrial waste in composite production is a possible solution for both problems. In this study, the potential use of talc, quartz and ceramic waste FFC fracture as a friction modifier in brake friction materials and its performance properties in accordance with industry requirements were investigated. The tribological, physical and mechanical properties of the brake pads were measured, and the friction surface morphology was investigated by scanning electron microscopy. According to the results obtained, the highest specific wear rate was observed in the FM3 sample. The FM2 sample with the highest hardness and average friction coefficient showed the lowest wear. FM4, FM5 and FM6 samples with high talc and quartz content exhibited low coefficient of friction characteristics compared to other samples.
