“…However, the difference in filler content has a great influence on the SWR, as the range of SWR of the composites with no filler is much higher than the composites with 8 and 16 wt% of filler. Similar effects of sliding velocity on the SWR of glass‐epoxy composites by Sarkar et al [ 49 ] and of carbon‐epoxy‐cenosphere hybrid composite by Arivalagan et al [ 50 ] are reported in the past. Identical results have been reported by the authors in their previous research on wear response study of glass‐polyester composites filled with marble dust using neural computation.…”

Marble dust generated during processing of the marble producing rocks is a major solid waste with a detrimental impact on environment. Analysis shows that this waste has constituents having compounds like SiO2, Al2O3, Fe2O3, CaO, MgO, etc., in different proportions. This paper explores on the possible use of waste marble dust as secondary filler in glass‐polyester composites and reports on its dry sliding wear characteristics. Such hybrid composites with unsaturated polyester as the matrix are fabricated by keeping the woven glass fibre loading fixed and by varying the weight fraction of the particulate filler, that is, marble dust through a simple hand layup route. Dry sliding wear trials are conducted under different test conditions as per ASTM G 99‐05 following the L30 model of response surface method (RSM). A parametric appraisal of the wear process is made using RSM and the significant control factors and their interactions influencing the specific wear rates are identified. Scanning electron microscopy of the worn composite surfaces is done to ascertain the wear mechanism. It is found that the presence of marble dust improves the wear resistance of unfilled glass‐polyester composites substantially. Further, prediction of wear rate of the composites for a wide range of filler content and sliding velocities is conducted using RSM and another prediction model based on fuzzy logic and the outcomes are compared.

“…It is clear in this formula, load and speed are effective on the friction force. Increasing sliding speed increased surface temperature and it caused a high adhesion between the contact surfaces [14,19,24]. High adhesion caused an increase of friction force, thus, increasing friction forces increased the wear rates as it is seen in Figures 4 and 5.…”

“…Therefore, the friction coefficients were decreased. Sarkar et al [19], explained that as a result of increasing load, it could be a transfer film because of heat generation of rubbing process, thus the friction coefficient decreases because of the increasing load. In the Figure 4, increasing sliding speed caused an increase of friction coefficient.…”

“…PPS polymer showed the highest wear rate, while 40 wt% reinforced PPS composite showed the minimum specific wear rate. In the literature, increasing speed increased the contact surface heat [19]. It is thought that increasing speed could cause the increasing of surface temperature of pin specimens due to the frictional heating and it could be result of melting the pin contact surfaces and it could increase the wear amount.…”

The aim of this study is the experimental investigate of wear and friction properties of polyphenylene sulfide polymer (PPS) and 20%, 30% and 40% by weight glass fiber reinforced polyphenylene sulfide composites. Tribological tests were done by pin-on-disc test configuration. The disc material is AISI 1040 steel. 50, 100, 200 N normal loads and 1, 2, 3 m/s speeds were applied to the test specimens. Adding fiber decreased the friction values and specific wear rates. Furthermore, increasing load decreased the friction coefficient but increased the specific wear rate, although increasing sliding speed increased both friction and specific wear rate.

A carbon/carbon–Al–Cu composite reinforced with carbon fiber 2.5D-polyacrylonitrile-based preforms was fabricated using the pressureless infiltration technique. The Al–Cu alloy liquids were successfully infiltrated into the C/C composites at high temperature and under vacuum. The mechanical and metallographic properties, scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive spectroscopy (EDS) of the C/C–Al–Cu composites were analyzed. The results showed that the bending property of the C/C–Al–Cu composites was 189 MPa, whereas that of the pure carbon slide material was only 85 MPa. The compressive strength of C/C–Al–Cu was 213 MPa, whereas that of the pure carbon slide material was only 102 MPa. The resistivity of C/C–Al–Cu was only 1.94 μΩm, which was lower than that of the pure carbon slide material (29.5 μΩm). This finding can be attributed to the “network conduction” structure. Excellent wettability was observed between Al and the carbon matrix at high temperature due to the existence of Al4C3. The friction coefficients of the C/C, C/C–Al–Cu, and pure carbon slide composites were 0.152, 0.175, and 0.121, respectively. The wear rate of the C/C–Al–Cu composites reached a minimum value of 2.56 × 10−7 mm3/Nm. The C/C–Al–Cu composite can be appropriately used as railway current collectors for locomotives.
