“…4 the least. However, every specimen has a slight difference in physical properties, given the rather similar wear rate, as noted earlier [11], A variation in porosity affects the performance of brake pad less than does a variation in hardness. Thus, the consideration of physical properties focused on hardness.…”

This study investigates the effects of mixing condition on hardness, porosity, specific gravity, wear, and friction characteristics of automotive brake materials. In the experiment, mixing raw materials with three different conditions of impeller speed (3000, 4500, and 6000 rpm), mixing duration (up to 8 min) and mixture loading based on a mixer volume (35, 50 and 65 vol% ) were determined using the formulated mixture composition. Homogeneity in terms of density values including hardness, porosity, and specific gravity of the finished brake pads were determined. The surfaces and the distribution of friction material were studied using scanning electron microscopy (SEM). The correlation between various mixing conditions and physical and tribological properties of brake pads were discussed and reported.

“…The third body layer resembles a continuous layer at a friction-based pair interface for all the brake pad materials, where energy transformation occurs. According to the viewpoint on the third physical layer, the friction pair interface of wear debris is trapped into a continuous sheet rather than particle isolation from the surface during the braking phase [166]. This layer is influenced by frictional heat, and a rotor film has known as transmission film, i.e.…”

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.

We report the synthesis and characterization of engineered PEEK‐based composites by using biochar (DDGS500—pyrolyzed Distiller's dried grains with soluble (DDGS)), metal (Mo), and PEEK‐ceramic (Xonotlite) as reinforcements. A systematic study was done to understand the effect of these additives on functional and mechanical properties. Initially, these composites were synthesized by hot pressing. Microstructure analysis of reinforcement powders by scanning electron microscopy (SEM). Detailed microstructure study of the composites showed that DDGS500 powder particulates were well dispersed within the PEEK matrix after the addition of 5 vol%. However, at higher concentration of 10 and 20 vol%, the particles segregated at the phase boundaries and PEEK rich cores were observed in the microstructure. Mo and Xonotlite particles were segregated at the phase boundaries even at 5 vol% concentration, which was more prominent at higher concentrations of 10 and 20 vol% reinforcements. Differential scanning calorimetry (DSC) showed lowering in melting point (Tm) and crystallization temperature (Tc) and increase in crystallization in all the composites. The addition of DDGS500 and Mo enhanced the plasticity and Ultimate Compressive Strength (UCS) (5 vol% additions of DDGS500 and Mo enhanced the UCS by 12.6% and 32.2%, respectively) of the composites whereas Xonotlite additions increased brittleness of the composites. The addition of DDGS500, PEEK‐Mo, and PEEK‐Xonotlite particulates lowered the wear rate until 10 vol% by several orders of magnitude and stabilized the friction coefficient (μ) versus distance profile. However, significant increase in wear rate at 20 vol% of Xonotlite was observed due to third body abrasion. All the composites showed hydrophobic behavior except PEEK‐20 vol% Xonotlite, which showed hydrophilic behavior with a decrease in contact angle as a function of time, which shows that Xonotlite can be a promising additive for increasing hydrophilicity of PEEK‐based composites for biomedical applications.
