“…This is agreed with the literature that PES and PI blend is adverse for the formation of stable transfer film. 3 The deformation of PES/PI and transfer film in friction interface is quite discontinuous and uneven as mentioned earlier, which will induce discontinuous and uneven load distribution in the friction interface.…”

“…Polymers are widely used in friction pairs ascribing to their excellent self-lubricating performance or wear resistance. [1][2][3][4] Such as polyimide (PI), polytetrafluoroethylene (PTFE), polyetheretherketone (PEEK), polyethersulfone (PES) and so on. Polymer composites with excellent tribological properties can be obtained by blending different polymers.…”

The synergistic effect of silica (SiO2) and copper (Cu) nanoparticles in polyimide (PI) on the friction interfacial deformation of polyethersulfone/polyimide (PES/PI) blends was studied. Results indicate that the effect of SiO2 and Cu nanoparticles on the tribological performance of PES/PI nanocomposites is quite different from each other. The addition of SiO2 nanoparticles into PI improves the antifriction of PES/PI nanocomposites by 24.4%, but has little effect on the wear resistance. The incorporation of Cu nanoparticles into PI enhances the wear resistance of PES/PI nanocomposites by 55.5%, but has little effect on the antifriction. PES/PI nanocomposites achieve the better comprehensive tribological performance when the content of SiO2 and Cu is 0.8 wt and 0.2 wt%, respectively. The friction interfacial deformation analysis reveals that SiO2 in PI improve the continuity and uniformity of deformation in friction interface and reduce the severe wear of transfer film. Cu nanoparticles in PI improves the continuity but not the ununiformity of deformation. Thus, the abrasive wear of counterpart ball is severe. The synergistic effect of SiO2 and Cu nanoparticles in PI improves the continuity and uniformity of friction interfacial deformation, which contributes to the improvement of friction and wear of PES/PI nanocomposites.

“…Overall these curves follow a similar pattern of variation, showing a fluctuating decline, with the friction coefficient decreasing from 300 C down to 200 C, increasing from 200 to 150 C and decreasing slightly from 150 to 100 C. It is worth noting that the friction coefficient of the rape straw fiber reinforced composite remained in the range of 0.40-0.49 during this test phase, meeting the standard requirements (0.20-0.70), and the good recovery performance is conducive to smooth braking during vehicle driving. 22…”

Reinforcing fibers play a key role in improving the tribological properties of friction polymer composites. Cellulose reinforcing fibers were extracted from rapeseed straw waste and prepared as friction composites based on wet granulation, and the effects of heat and rapeseed straw fiber (RSF) additions on the tribological properties were systematically investigated. The addition of RSF induced an important transformation of the major wear mechanism to abrasive wear, especially at 9 wt%, where the abundant tribo‐films contributed to the stability of the friction coefficients (fade rate 6.8%, recovery rate 106.6%), resulting in a 37.5% increase in wear resistance compared to no addition. Furthermore, XRD, FTIR and SEM analyses showed that the silane‐ethanol solution modification contributed to the good performance of RSF.Highlights Rapeseed straw fiber (RSF) and granulation technology for polymer composites. Addition of RSF transforms adhesive and fatigue wear into abrasive wear. Friction models are developed to clarify the wear mechanism transformation. A 37.5% increase in wear resistance was achieved when RSF was added at 9 wt%.

“…Phenolic is also one of the essential ingredients used in friction material as it is a strong binder, and high-strength binders improve the overall friction materials’ performance [ 9 ]. There is literature that discusses the improvement of phenolic’s properties when reinforced with fillers such as alumina, calcium carbonate, silicon carbide, talc, copper, carbon black, graphite, and CNTs [ 10 , 11 , 12 ].…”

Hybrid fillers can be produced via various methods, such as physical mixing and chemical modification. However, there is a limited number of studies on the effect of hybridisation on the mechanical performance of hybrid filler-reinforced polymer composites, especially in the context of wear performance. This study investigated the wear resistance of carbon nanotubes (CNTs)/alumina hybrid-filled phenolic composite, where two hybrid methods were used to produce the CNTs/alumina hybrid filler. The CNTs/alumina (CVD hybrid) was synthesised using the chemical vapour deposition (CVD) method, whereas the CNTs-/alumina (physically hybrid) was prepared using the ball milling method. The CNTs/alumina hybrid filler was then used as a filler in the phenolic composites. The composites were prepared using a hot mounting press and then subjected to a dry sliding wear test using a pin-on-disc (POD) tester. The results show that the composite filled with the CVD hybrid filler (HYB composite) had better wear resistance than the composite filled with physically hybrid filler (PHY composite) and pure phenolic. At 5 wt%, the HYB composite showed a 74.68% reduction in wear, while the PHY composite showed a 56.44% reduction in wear compared to pure phenolic. The HYB composite exhibited the lowest average coefficient of friction (COF) compared to the PHY composite and pure phenolic. The average COF decreased with increasing sliding speeds and applied loads. The phenolic composites’ wear and average COF are in the order HYB composite < PHY composite < pure phenolic under all sliding speeds and applied loads.
