“…The dominant wear mechanism in this regime is the ironing mechanism and there is not sufficient load to deform the specimen that would increase the wear. A strong bond between the fiber and the matrix made the separation of material from the pin more difficult and contributes to the higher wear resistance [18].…”

Abstract:The goal of this work is to study the wear behavior of materials that have the potential to be used as brake pad materials under different contact loads and speeds instead of asbestos. The three different brake pad materials studied are flax fiber reinforced phenolic composites (FFRC), basalt fiber reinforced phenolic composites (BFRC), and flax/basalt reinforced hybrid phenolic composites (HFRC). A wear mechanism map was developed by using the fuzzy c-means clustering algorithm method (FCM) to study the wear mechanism of composites. The results showed BFRC to be a better brake pad material than the other fiber reinforced composites studied, because the good thermal characteristics and bonding nature of basalt fiber increased the wear resistance of BFRC considerably.

“…Some micro-particles such as Ag 2 S, CuS, NiS, SiC and Cr 3 C 2 have been reported to improve the wear resistance of PPS, but others like PbTe, PbSe, ZnF 2 , SnS and Al 2 O 3 have been found to exercise an adverse influence [7][8][9][10][11][12]. The concept of adding particles of sub-micro-or nano-scale into polymers is one of the most intriguing subjects in the recent decades.…”

Study on friction and wear behavior of polyphenylene sulfide composites reinforced by short carbon fibers and sub-micro TiO particles. Composites Science and Technology, Elsevier, 2009, 68 (3-4) AbstractPolyphenylene sulfide (PPS) composites filled with short carbon fibers (SCFs) (up to 15 vol.%) and sub-micro-scale TiO 2 particles (up to 7 vol.%) were prepared by extrusion and subsequently injection-molding. Based on the results of sliding wear tests, the tribological behavior of these materials was investigated using an artificial neural network (ANN) approach. A synergistic effect of the incorporated short carbon fibers and sub-micro TiO 2 particles is reported. The lowest specific wear rate was obtained for the composition of PPS with 15 vol.% SCF and 5 vol.% TiO 2 . A more optimal composition of PPS with 15 vol.% SCF and 6 vol.% TiO 2 was estimated according to ANN prediction. The scanning electron microscopy (SEM) observation revealed that this hybrid reinforcement could be interpreted in terms of a positive rolling effect of the particles between the two sliding surfaces, which protected the short carbon fibers from being pulled out of the PPS matrix.

“…In previous study, PPS formed a thick and grainy transfer film on the counterface during sliding, but the transfer films became thin and uniform with the addition of many fillers and/or reinforcement materials. 14,15) It was thus expected in this study that CNTs would promote the formation of uniform and thin transfer film during sliding. Figure 5 shows the transfer films taken by optical microscopy.…”

The flexural and tribological performance of polyphenylene sulfide (PPS) composites reinforced with multi-walled carbon nanotubes (MWCNTs) were studied as a function of carbon nanotube (CNT) proportion. The composites were prepared by compression molding and were tested for friction and wear in a pin-on-disk sliding configuration against hardened tool steel of a hardness of 55-60 HRC. The lowest specific wear rate of 15:86 Â 10 À6 mm 3 /Nm was obtained for the PPS-0.2%CNT composite. The variation in coefficient of friction was practically insignificant, irrespective of CNT proportion. The transfer films formed on the counterface during sliding were examined by optical microscopy and atomic force microscopy (AFM) to investigate the characteristics of transfer film in terms of topography and texture of transfer film. The worn pin surfaces were also examined by AFM to study the behavior of wear and friction of the composites. Three-point flexural tests and hardness measurements were carried out for PPS-CNT composites, where CNT concentration varied from 0.2 to 10 vol%. The highest flexural strength was observed in the PPS-0.2%CNT composite. The change in flexural strength with CNT proportion is discussed in terms of surface hardness and structural integrity of the composites examined by scanning electron microscopy (SEM).
