“…The pin-on-disk method was utilized to examine the abrasive wear of the test samples. Additionally, Al/Al 2 O 3 submicron composite materials were tested for their tribological characteristics for a brake rotor containing material made of semimetallic substances, along with determining their Vickers hardness and density values [46].…”

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.

“…It is also inexpensive and simple to create in large quantities and to strict standards. The primary disadvantage of this material is its high density, which contributes to increased vehicle weight, CO 2 emissions, and poor handling performance [2,3]. Brake rotors add a substantial amount of weight to the chassis.…”

In an automotive vehicle, the brake discs, also known as rotors, contribute significant weight to the engine chassis. Hence, lightweight aluminum brake discs are in the developmental stage as a popular alternative to traditional cast iron or steel brake discs. Weight reduction is desirable to improve vehicle performance and fuel efficiency. Monolithic aluminum is not a practical choice as an alternative to existing commercial brake discs because of its poor operational temperature and wear performance. Literature suggests that Aluminum Metal Matrix composite (AMC) can be an ideal choice for brake discs. AMC brake discs are more resistant to warping and cracking than cast iron discs. They also have better heat dissipation properties, which help reduce brake fade and prolong the life of the brake pads. This study examines the different types of aluminum alloys, reinforcements, and manufacturing processes for manufacturing ideal AMC brake discs. The significance of silicon as the principal alloying element to improve thermal characteristics and incorporate various reinforcements to increase the AMC's wear resistance and frictional stability for brake disc applications is outlined. This article focuses on the thermal and tribological behavior of the AMC brake discs' performance over traditional rotors. The review discusses the different equipment required to assess the tribological characteristics of brake discs to meet industrial requirements. In addition to experimental validation, this paper addresses the necessity of proper rotor design selection and numerical analysis to evaluate the thermo-mechanical behavior of the brake disc at various braking events. The article points out that aluminum metal matrix composites have great potential to replace conventional grey cast iron brake discs. Finally, this review discusses possible future research avenues for developing an AMC rotor disc.

“…The brake pad material operates at a substantially lower temperature because of the superior heat dissipation of the Al/Al 2 O 3 submicron combination. Brake pad material was found to have a 20% greater coefficient of friction when sliding against gray cast iron up to 2 m/s [ 24 ].…”

Analysis of mechanical and thermal behaviors during braking has become an increasingly important issue in many transport sectors for different modes of transportation. Brake failure generated during braking is a complex phenomenon confronting automobile manufacturers and designers. During braking, kinetic energy is transferred to thermal energy, resulting in the intense heating of disc brake rotors that increases proportionally with vehicle speed, mass, and braking frequency. It is essential to look into and improve strategies to make versatile, thermally resistant, lightweight, high-performance discs. As a result, this study uses the finite element method to conduct a thermo-mechanical analysis of aluminum alloy and aluminum matrix nano-composite disc brake rotors to address the abovementioned issues. The FEA method is used for the thermo-mechanical analysis of AMNCs for vented disc brake rotor during emergency braking at 70 km/h. From the results obtained, aluminum base metal matrix nano-composites have an excellent strength-to-weight ratio when used as disc brake rotor materials, significantly improving the discs’ thermal and mechanical performance. From the result of transient thermal analysis, the maximum value of heat flux obtained for aluminum alloy disc is about 8 W/mm2, whereas for AMNCs, the value is increased to 16.28 W/mm2. The result from static analysis shows that the maximum deformation observed is 0.19 mm for aluminum alloy disc and 0.05 mm for AMNCs disc. In addition, the maximum von Mises stress value of AMNC disc is about 184 MPa. The maximum von Mises stress value of aluminum alloy disc is about 180 MPa. Therefore, according to the results, the proposed aluminum base metal matrix nano-composites are valid for replacing existing materials for disc brake rotor applications.
