“…They are designed to substitute harmful asbestos brake pads. NAO brake pads have a low braking noise and a low wear rate (1) . However, they do not work well at high temperatures because they lose braking efficiency, which is known as brake fade phenomenon (2) (3) .…”

This experimental study aimed to assess the friction performance of nonasbestos organic (NAO) brake pad based on ternary combinations of rockwool, PAN, and cellulose fibers under fade-recovery conditions. Four compositions with varying volume fractions of rockwool, PAN, and cellulose fibers were fabricated. The tribological properties of the sample were tested using JF160 Chase tester based on SAE J661. Optimally, the sample with a synergistic combination of rockwool, PAN, and cellulose fibers in proportion of 10:4:4 vol.% exhibited the best overall friction performances. This combination could be used as NAO brake pad material for reliable, efficient, safe, and comfortable braking operations.

“…In this case, the significant increase in their both the elastic modulus and yield strength was possible due to the enhanced interfacial adhesion. The reason was that load was transferred to the greater degree (and simultaneously over the large space) from the polymer matrix to reinforcing fibers [50].…”

The tribomechanical properties of the wear-resistant ultrahigh molecular weight polyethylene (UHMWPE)-based composites loaded with wollastonite microfibres silanized with various coupling agents (“KH-550”, “Penta-1006”, and “OTS”) were investigated. It was demonstrated that the mechanical properties of UHMWPE-based composites filled with various amounts of wollastonite (7–23 wt. %) increased by 1.3 times (yield strength) and by 1.8 times (elastic modulus), while the wollastonite silanization further improved yield strength by 9% in some cases. It was demonstrated that the composite loaded with 23 wt. % wollastonite silanized with the “KH-550” coupling agent possessed the maximum wear resistance under “moderate” conditions of tribological loading. Under “severe” conditions, the composites containing 23 wt. % wollastonite silanized with the less efficient “OTS” and “Penta-1006” agents showed the greatest wear resistance during dry sliding friction. Wear resistance significantly depended on filler weight fraction and the load–speed mode of the tribological tests. Based on the obtained experimental data on the mechanical (including impact toughness) and tribological properties of the UHMWPE-based composites loaded with wollastonite, the optimal compositions (the filler content and the type of the coupling agent) for two load–speed modes were designed using the developed computer algorithm. The composites provided the predefined high tribomechanical properties for operation in the metal-polymer friction units compared to neat polymer.

“…The constituent materials are weighed according to the three specimen compositions described in Table 1. The preparation of the specimens includes; the composition weighing process, the next mixing process is the cold moulding process and the hot moulding process [7]. First, the ingredients were mixed for eight minutes using an electric mixer on a gradual speed setting to produce a homogeneous mixture.…”

In this paper, waste glass powder (GP) is selected as a sustainable abrasive to replace pure silica minerals. XRF analysis to determine the content of glass waste. Composite specimens have volume fraction ratios of 0%, 2%, and 4% GP evaluated with TGA, Pin on Disc friction test, and Hardness Rockwell type R. Scanning electron micrograph (SEM) observe the formation of abrasion and surface wear of the specimen. The results of the X-ray fluorescence (XRF) glass powder waste obtained that the main content of silicon dioxide (SiO2) was 65.58%. Thermogravimetry (TG) showed that the thermal resistance of the composite from the addition of glass powder increased. Glass powder as an abrasive shown that increase the coefficient of friction brake friction materials. The presence of glass powder increases the hardness of the composite, and the coefficient of wear rate of the composite decreases.
