Copper-based functionally gradient composite material is developed using powder metallurgy processing technique, as a potential wind turbine brake pad material. The developed composite has a gradient composition of Cu, CeO 2 , Al 2 O 3 , Fe, and C g to enable joint strength at the interface (brake calliper) and wear resistance at the contact surface (brake disc). The article presents a comprehensive analysis on the microstructure, microhardness, and tribological performance of the developed composite. The wear mechanism is deduced through surface morphology, elemental composition, and phase composition analysis using field emission scanning electron microscope, energy dispersive X-ray spectroscope, X-ray diffractometer, and X-ray photoelectron spectroscope. A maximum hardness of 198.2 HV was obtained at the contact surface. Experimental values from tribology tests show that a decreasing trend was obtained with a wear rate of 2.013 × 10 −7 g N-m −1 and a friction coefficient was 0.215.

“…It exhibits an unstable friction coefficient and higher wear loss at high braking speeds (>200 km/h). Kumar et al analyze the properties of sintered Cu-Sn brake pads used in harsh environments and off-road purposes [84]. These have a low wear rate, high shear strength, and good frictional properties.…”

The proper functioning of automotive brake pads is of utmost importance to ensure the safety of passengers. Therefore, brake pad materials must be chosen with utmost precision and care to ensure their optimal functioning for long durations. Through a thorough literature review, it is found that the materials used currently for this purpose pose multiple discrepancies. Therefore, it is imperative to shift our focus towards nanomaterials, as they are one of the essential novel materials in this field. This study discusses the multiple constituents used in commercial brake pads, their role in improving and stabilizing their operation, and their desired properties to achieve optimal functioning. Parallelly, this study also reviews some of the potential organic and carbon nanomaterials that could prove to provide tough competition to currently utilized materials for brake pad applications. From this review, the major future commercial brake pad materials obtained include the likes of banana peel powder, crab shell powder, coconut fibers, stark corn fibers, metal oxide composites, metal nitride composites, multiwalled carbon nanotubes, and hybrid nanocomposites. These materials are studied on the basis of their performance under high-frictional force applications and analyzed by considering their mechanical, chemical, thermal, and tribological properties. Carbon nanotube-based composites showed improved tribological and braking performances making them more attractive than the materials in commercially available brake pads. In addition to these, the effects of usage of such nanomaterials on the environment and health are reviewed, in order to understand the feasibility of utilization of nanomaterials in automotive brake pad applications. From this analysis, this work suggests that there are a variety of nanomaterials that prove to be capable of automotive brake pad applications and, with further research and technological developments, would prove to be an asset to the automotive brake pad industry.

“…For example, SEM-EDXS (under group) and TEM-EDXS (under group) results will increase reliability for experiments [205,206] by obtaining identical or compatible results [207,208]. As far as TEM is concerned, it is one of the complete characterization tools for nanostructured structures [209,210]. The preparation of the samples can be complicated, and one way is to prepare an ethanol wear suspension, which would deposit a single drop into the grid of TEM Gold [211] or Cu [212].…”

The composite materials are fabricated by combining various ingredients to make higher material properties as required by various industries. The primary classification of composites is based on their build ingredients, such as binder, fibre, reinforcement and fillers. The characteristics of individual ingredients influenced the properties of composites. Further, friction materials are those composite materials efficiently used in vehicles' braking.Researchers have tried the various formulations of friction materials because it is very significant to study the mechanism and material characteristics due to the safety measures of vehicles. The current study examines the various brake composite materials' characteristics and their mechanical and tribological performance in this article. The tribological study includes the various terminologies used in friction and wear using pin-ondisc, dynamometer, field studies, etc. The effects of numerous elements impacting the wear of frictional materials are given, and the tribological performances of used friction materials are given the utmost attention.
