“…The accumulation of SCF and KF in polymer compounds indicates easier shear and degradation. It improves the values of %F and %R, as described in the literature [46][47][48][49][50]. The rising proportion of SCF in polymer mixtures creates a discrepancy matrix; in tribal experiments, it may be caused to generate extra wear particles and debris (act as the third body) among the frictional boundaries and enhance the performance [46].…”

Recently, much research has revealed the increasing importance of natural fiber in modern applications. Natural fibers are used in many vital sectors like medicine, aerospace and agriculture. The cause of increasing the application of natural fiber in different fields is its eco-friendly behavior and excellent mechanical properties. The study’s primary goal is to increase the usage of environmentally friendly materials. The existing materials used in brake pads are detrimental to humans and the environment. Natural fiber composites have recently been studied and effectively employed in brake pads. However, there has yet to be a comparison investigation of natural fiber and Kevlar-based brake pad composites. Sugarcane, a natural fabric, is employed in the present study to substitute trendy materials like Kevlar and asbestos. The brake pads have been developed with 5–20 wt.% SCF and 5–10 wt.% Kevlar fiber (KF) to make the comparative study. SCF compounds at 5 wt.% outperformed the entire NF composite in coefficient of friction (µ), (%) fade and wear. However, the values of mechanical properties were found to be almost identical. Although it has been observed that, with an increase in the proportion of SCF, the performance also increased in terms of recovery. The thermal stability and wear rate are maximum for 20 wt.% SCF and 10 wt.% KF composites. The comparative study indicated that the Kevlar-based brake pad specimens provide superior outcomes compared to the SCF composite for fade (%), wear performance and coefficient of friction (Δμ). Finally, the worn composite surfaces were examined using a scanning electron microscopy technique to investigate probable wear mechanisms and to comprehend the nature of the generated contact patches/plateaus, which is critical for determining the tribological behavior of the composites.

“…The reason for this is that when the proportion of PPTA is too high, the bers tend to agglomerate and clump together, which leads to a reduction in the bonding strength between the bers and the matrix. And the presence of loose bers on the surface of the material can increase friction and even cause localized heat concentration and wear 30 .…”

To improve the friction and wear performance of polyetheretherketone (PEEK). In this paper, a low-friction PEEK-based composite with PEEK as the matrix material, polytetrafluoroethylene (PTFE) as the solid lubricant, and poly-p-phenylene-terephthamide (PPTA) as the reinforcing material were prepared by compression molding technique, and then the optimal preparation condition for PEEK was gained by exploratory experiments. Finally, the tribological performance of PTFE/PPTA/PEEK composites was researched under dry friction and oil lubrication conditions. The microstructure of the wear mark was observed by scanning electron microscope and white light interference microscope, and the wear mechanism of PEEK and its composites under different lubrication conditions were analyzed. The results show that the main wear mechanisms of the friction pair consisting of PTFE/PPTA/PEEK composites and bearing steel are ploughing and adhesive wear. When the friction pair slides, PPTA reduces the wear of the composite caused by its high fiber strength and good thermal stability, and the coefficient of friction (COF) is reduced because the PTFE on the surface is pressed into a smooth, solid lubricating film. Whether under dry friction or oil lubrication conditions, the PEEK composites containing 25wt% PTFE and 6wt% PPTA both have the lowest wear and lower COF.

The lessening pattern in the values might be the reason for the tribo-interfaces process.…”

Organic fibers are utilized these days in many applications because of their great mechanical properties. Organic fibers have replaced the synthetic fibers in various places. Previous research articles have told the potential of natural fiber reinforcement as a brake friction material, but there are very few research articles of comparative study of standard brake friction materials and natural fibers. So in this research paper, a unique Sabai grass fiber was used as a brake friction material to develop new samples of brake pads and compare with standard Kevlar-based composites. The brake pads were formed by utilizing the different percentages of Kevlar fiber (standard material) (5%-10%) and Sabai grass fibers (5%-20%) in the hydraulic brake producing machine. The fundamental point of this investigation is to track down the substitute of asbestos and Kevlar in brake material. The outcomes of physico-mechanical properties revealed that percentage of porosity, percentage of water retention, percentage of compressibility increments as augmentation the level of Sabai grass fiber and Kevlar fiber in the polymer composite while Ash, hardness and density diminishes with increment level of Sabai grass fiber and Kevlar fiber in the composite. The Sabai grass based composites with 5 wt% have shown improved outcomes for (μ) coefficient of friction, % fade and for wear among all organic fiber composites while the results in terms of wear and recovery were seen to increment with increment level of Sabai grass fiber. In relative examination it has been determined that Kevlar based Brake pad specimen showed minimal better outcomes in % fade, (μ) coefficient of friction and wear than that of Sabai grass fiber composites.The mechanical properties of sabai grass fiber and Kevlar-based composites have shown nearby results. The wear rate and thermal stability were verified most elevated for 20% Sabai grass composites and 10% Kevlar mixture.
