“…This indicates that the composite FMHF with helical-shaped fibers exhibited improved frictional stability, followed by the composite FMUF with undulated-shaped fibers. It is understood that the fade and recovery behaviors of fiber-reinforced composite materials are mainly related to the stability of the friction interface, especially the improved fiber–matrix bonding strength and the generated secondary plateaus [ 6 , 41 , 42 ]. A detailed discussion about the friction surface topography of the tested composite materials is given in Section 3.3 .…”

In this paper, we aim to evaluate the tribological, mechanical, and morphological performance of resin-based friction composites reinforced by sisal fibers with different shapes, namely helical, undulated, and straight shapes. The experimental results show that the shape of the sisal fibers exerts a significant effect on the impact property of the composite materials but no obvious influence on the density and hardness. The friction composite containing the helical-shaped sisal fibers exhibits the best overall tribological behaviors, with a relatively low fade (9.26%), high recovery (98.65%), and good wear resistance (2.061 × 10−7 cm3∙N−1∙m−1) compared with the other two composites containing undulated-shaped fibers and straight-shaped fibers. The impact fracture surfaces and worn surfaces of the composite materials were inspected by scanning electron microscopy, and we demonstrate that adding helical-shaped sisal fibers into the polymer composites provides an enhanced fiber–matrix interface adhesion condition and reduces the extent of fiber debonding and pullout, effectively facilitating the presence of more secondary plateaus on the friction surface, which are responsible for the enhanced tribological and mechanical properties. The outcome of this study reveals that sisal fibers with a helical shape could be a promising candidate as a reinforcement material for resin-based brake friction composite applications.

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.

“…Lot of isolated wear particles are seen throughout the surface. This is due to the higher amount of heat generated at the interface, causing the less heat resistance particles to degrade along with the phenolic resin 45,46 which is an evident from the oxidation product through the surface from the elemental mapping.…”

The purpose of friction material is to decelerate a vehicle by transforming the kinetic energy of the vehicle into heat, via friction, and dissipating that heat to the surroundings. A lot of heat is generated at the contact plateaus formed by the reinforcing fibers. Therefore, inorder to dissipate the heat, steel fibers were coated with FeS and SnS and accordingly brake pads were made and termed as DBF and DBS. Another brake pad with similar formulation but with a mixture of steel fiber, FeS and SnS was made (designated as DBO) for comparison. All three brake pads were tested in an inertia brake dynamometer with a typical schedule. The speed spread (100/50 Kmph) 0.6g and effectiveness variation of all the pads are fallen in the required range. The fade I of DBO is observed 32.8% lesser whereas for DBS and DBF, it is observed10% and 15.7% more than the standard values, respectively. DBF and DBO have shown 25.4% and 39.6% more wear than DBS, respectively. Further, it is observed a more consistent µ during single braking to identify fade during stops in the second effectiveness test. It is evidenced for the increase in the life of the friction film formed by the sulfide coated fibers in DBS which has increased its wear resistance (Max Δµ = 0.10 for DBS, 0.29 for DBF, and 0.30 for DBO). It is also noticed that the radial wear of all three brake pads was greater than the tangential wear and their ratios are 1.36, 1.40 and 1.55, respectively for DBS, DBF and DBO. Moreover, the optimization has revealed the DBS as best performer friction materials formulation.
