An experimental investigation was carried out to study the influence of fiber orientation on the wear and frictional characteristics of hybrid-epoxy composites. Unidirectional and bidirectional glass-carbon epoxy(GC) and Twaron-carbon epoxy (TC) composites were prepared using conventional wet hand-layup technique followed by vacuum bagging using an amine and an anhydride based curing agents. Wear and frictional tests were carried out with configuration of a pin on a rotating disc at normal loads of 30, 50 and 80N under dry sliding speed of 3 and 8 m/s. It was found that hybrid composites containing bidirectional yarn systems have better wear resistance, lower wear loss and higher frictional coefficient compared to the unidirectional hybrid composites independent of the load, speed, nature of the fibers and hardener. TC composites were also found to exhibit better mechanical properties compared to GC composites. Scanning electron microscope (SEM) examination revealed that the fiber orientation has considerable effect on the wear, friction properties of hybrid composites and failure mode initiation.

“…Therefore, polymers and their composites, e.g., nylon and rubber, have been widely used to produce water-lubricated bearings and gears [3]. And investigations on the tribological behaviors of polymers in aqueous environments have been also reported by many researchers [4][5][6][7][8][9][10]. It has been found that aqueous mediums affect the tribological behavior of polymers mainly from the following several aspects.…”

The friction and wear behavior of ultra-high molecular weight polyethylene (UHMWPE) sliding against GCr15 steel and electroless Ni-P alloy coating under the lubrication of seawater was investigated and compared with that under dry sliding and lubrication of pure water and 3.5 wt.% NaCl solution, respectively. It was found that under the lubrication of aqueous medium, the friction and wear behavior of UHMWPE mainly depended on the corrosion of counterface and the lubricating effect of the medium. Because of serious corrosion of counterface by the medium, the wear rates of UHMWPE sliding against GCr15 under the lubrication of seawater and NaCl solution were much larger than that under other conditions, and such a kind of wear closely related to the corrosion of counterface can be reckoned as indirect corrosive wear. However, when sliding against corrosion-resistant Ni-P alloy under the lubrication of seawater, the lowest coefficient of friction and wear rate of UHMWPE were obtained, owing to superior lubricating effect of seawater. Moreover, periodic ripple patterns were observed on the worn surfaces of UHMWPE sliding against GCr15 under the lubrication of seawater and NaCl solution, which were ascribed to the intelligent reconstruction of surface microstructure of UHMWPE upon large plowing effect of the counterface asperities. Based on scanning electron microscopic (SEM) and three-dimensional (3D) profile analyses of the worn surfaces of UHMWPE, a stick-slip dynamic mechanism was proposed to illustrate the pattern abrasion of UHMWPE.

“…6(b)). We deduced that the cooling effect of water hindered the melting of the phenolic resin and inhibited the transfer and generation of wear debris on the sliding counterpart pin [22]. Under the sea water-bathed sliding condition, the surface of the counterpart pin after testing was much smoother and had no continuous covering of transfer film.…”

A Nomex fabric/phenolic composite was prepared, and its tribological properties were evaluated under dry and water-bathed sliding conditions by a pin-on-disk tribometer. The resulting size of the friction coefficient for the Nomex fabric/phenolic composite in the study occurred in the following order: dry sliding condition > distilled water-bathed sliding condition > sea water-bathed sliding condition. The fabric composite's wear rate from high to low was as follows: distilled water-bathed sliding condition > sea water-bathed sliding condition > dry sliding condition. Under water-bathed sliding conditions, penetration of water into the cracks accelerated the composite's invalidation process, resulting in a higher wear rate. We also found that the extent of corrosion and transfer film formed on the counterpart pin significantly influenced the wear rate of the Nomex fabric composite. Discussion of the Nomex fabric composite's wear mechanisms under the sliding conditions investigated is provided on the basis of the characterization results.
