Metallic fillers play a significant role in the brake friction material formulation due to its high thermal conductivity, tribo-load bearing ability against the rotor, friction stability and wear resistance. Brass powder is widely used in the formulation because of good thermal conductivity, fade and wear resistance. The commercial brass composed of 70 wt.% copper and 30 wt.% zinc. In this work, the brass powders with identical morphology and different weight percentage (wt.%) copper and zinc content is evaluated for its tribological and physico-mechanical performance in the brake friction material formulation. Three set of brake friction pads were fabricated with three different brass powders of varying copper and zinc content, 60% Cu-40% Zn, 70% Cu-30% Zn, and 80% Cu-20% Zn, respectively. The objectives of this study were to find the physico-mechanical properties based on Indian Standard IS 2742 and tribological performance of the brake pads based on ASTM G99-95 using pin-on-disc tribometer. The wear mechanism of the brake composite of worn surface was studied using scanning electron microscope. The brake friction composites were ranked based on extension evaluation method by considering the tribo-mechanical performance parameters. It is observed that brass with 80% Cu and 20% Zn proved to be the best performer based on the weighted average dependent degree of extension evaluation.

“…In addition, the friction temperature rise by increased speed reduces the surface mechanical property as found by [24,25]; even surface softening but invariably increases the resistance to deformation. Moreover, presence of steel fiber abrades the friction film formed which was responsible for µ stabilization [17].…”

“…In fact, it is interesting to point out that among the contaminants considered to be relevant for the first two principal components are Pb, reflecting the historical use of leaded gasoline (Albanese & Cicchella, 2012), Sb and Sn, which have been associated (together with Cd and Zn) with motor vehicle non-exhaust emissions (Adamiec et al, 2016) such as tires (Councell et al, 2004) and brake pad consumption (Grigoratos & Martini, 2015;Sathickbasha et al, 2019). Furthermore, the PCA biplot (Fig.…”

In 2017, a geochemical survey was carried out across the Commune of Santiago, a local administrative unit located at the center of the namesake capital city of Chile, and the concentration of a number of major and trace elements (53 in total) was determined on 121 topsoil samples. Multifractal IDW (MIDW) interpolation method was applied to raw data to generate geochemical baseline maps of 15 potential toxic elements (PTEs); the concentration–area (C-A) plot was applied to MIDW grids to highlight the fractal distribution of geochemical data. Data of PTEs were elaborated to statistically determine local geochemical baselines and to assess the spatial variation of the degree of soil contamination by means of a new method taking into account both the severity of contamination and its complexity. Afterwards, to discriminate the sources of PTEs in soils, a robust Principal Component Analysis (PCA) was applied to data expressed in isometric log-ratio (ilr) coordinates. Based on PCA results, a Sequential Binary Partition (SBP) was also defined and balances were determined to generate contrasts among those elements considered as proxies of specific contamination sources (Urban traffic, productive settlements, etc.). A risk assessment was finally completed to potentially relate contamination sources to their potential effect on public health in the long term. A probabilistic approach, based on Monte Carlo method, was deemed more appropriate to include uncertainty due to spatial variation of geochemical data across the study area. Results showed how the integrated use of multivariate statistics and compositional data analysis gave the authors the chance to both discriminate between main contamination processes characterizing the soil of Santiago and to observe the existence of secondary phenomena that are normally difficult to constrain. Furthermore, it was demonstrated how a probabilistic approach in risk assessment could offer a more reliable view of the complexity of the process considering uncertainty as an integral part of the results.

The type of binder and its fraction in the brake pad material formulation plays a vital role in fulfilling the key requirements of friction materials (FMs). Three set of brake pads were fabricated with 10, 12 and 14 weight percentage (wt%) of Epoxy-Modified novalac Phenolic (EMP) resin and designated as DB10, DB12, and DB14 respectively. The characterization of resin and composites were done using standard techniques. The tribological tests were carried out on an Inertia Brake Dynamometer (IBD) following industry standards JASO C-406 and JASO C-427. The friction and wear behavior based on the rotor temperature, rotor speed, and pad pressure was analyzed. It was observed that DB10 showed 12.8 % more thermal stability, 37.01 % more fade resistance and 11.54 % improved recovery rate than DB14. DB14 showed high wear resistance at 100, 200 and 300 °C for the speed of 50 km/h.
