“…[ 33,34 ] Kumar and Anand had done a lot of work on ramie fiber reinforced polymer composites: the mechanical properties of epoxy composites by reinforcing Indian ramie fiber had been improved [ 35 ] ; the experimental findings showed that reinforcement of ramie (Boehmerianivea) fiber into epoxy matrix significantly improved the wear resistance of neat epoxy. [ 36 ] On the one hand, the mechanical strength of SF/UHMWPE material were increased because the fiber fillers embedded in the matrix tightly and the wear resistance was improved either. [ 37 ] On the other hand, the SF in the UHMWPE matrix could be seen as bulges on the worn surface, a large number of SF bulges reduced the contact area and supported part of the applied load.…”

The ultrahigh-molecular-weight polyethylene (UHMWPE) has become the most widely used material for water-lubricated bearings. In the research, the effects of introducing sisal fiber (SF) filler materials on the friction and wear characteristics of UHMWPE-based composites were investigated. The composites were tested against the QSn7-0.2 copper disc, under water-lubricated conditions, using a specially designed testing apparatus. The purpose was to identify an improved material which could be used in water-lubricated bearings. Four types of composites were tested under different sliding velocities and applied loads, which included pure UHMWPE and 10, 20, and 30 wt% SF reinforced UHMWPE. The friction coefficient and wear amount were measured to characterize the tribological properties of these composite materials. Moreover, in order to reveal the primary mechanism involved in friction and wear, various surface characterization techniques were adopted on the surface of composite materials. The analysis results showed that the addition of SF can stabilize the frictional properties and increase the water absorption of SF/UHMWPE composites. Furthermore, the use of a proper percentage of SF can discharge the wear debris, improve the loading capacity, and reduce adhesion wear. The adding of 10% SF in UHMWPE had produced the best anti-friction properties at low speed and heavy load. This work can serve as a reference for the design of hydrophilic fiber reinforced polymer composites to reduce wear and improve lubrication performance.

“…[3,14,51] The addition of glass fiber, h-BN and PJ in the epoxy increased the strength, stiffness and load bearing capacity of the matrix thereby the composites are produced excellent tribological performance. [3,39] These enhancement in the properties are mainly attributed to very strong interfacial bonding between pure epoxy and other added fillers. This bonding is possibly due to the minimum difference in coefficient of thermal expansion (CTE) between matrix and fiber during fabrication of composites.…”

“…On the other hand, the natural fibers also contributed much on tribological performance of the polymer-based composites due to enhanced interfacial adhesion, load bearing capacity, and good mechanical properties.

The formation of transfer layer especially in polymer-based composites is unavoidable and essential to investigate the effectiveness of transfer layer under working conditions as it decides the material removal between mating parts. The main aim of the present work is to analyze the performance of transfer layer on specific wear rate (SWR) and coefficient of friction (COF) during dry sliding of hexagonal boron nitride (h-BN)/prosopis juliflora (PJ) reinforced polymer matrix composite. The mechanical test results exhibited that 136.4%, 145.7%, and 106.2% improvement in hardness, tensile and flexural properties of the hybrid composites compared to pure epoxy. Pin on disc wear test results showed that 15 wt% of h-BN and 5 wt% of PJ reinforced hybrid composite produced better wear performance of minimum COF as 0.0912 and SWR as 0.0000151 mm 3 /Nm. ANOVA analysis results showed that load is major contributing parameter on COF and SWR and their percentage of contribution as 25.40% and 79.38% respectively. Worn surface analysis revealed that the reason behind transfer layer formation and its effectiveness under sliding conditions. The major wear mechanisms are identified as micro cutting and micro plowing followed by matrix crack, fiber debonding, and fiber pull out.

“…Meanwhile, when alumina was used as fillers, jute/epoxy composites exhibited lowest CoF when compared with the composites containing SiC fillers. [29,30] From some of the experimental studies, it was found that the values of wear and CoF increased when more number of Kevlar fiber layers were used while investigating monolithic bamboo and bamboo/kevlar hybrid composites. [31] The NaOH treated and untreated fiberreinforced composites were analyzed for their tribological behavior and found that the more influential factors are in the order of load, speed, and sliding distance.…”

Recent era witnessed a tremendous growth in utilization of plant fibers to make composite materials, and their industrial applications have multiplied many folds. All these utilizations were kindled by the advantageous features of the plant fibers and their potential to substitute the currently used synthetic fibers in almost all the applications. Current work falls in line with the abovementioned statements, and Calotropis gigantea fibers (CGFs) are reinforced with epoxy matrix to fabricate composite materials. The fiber surfaces were modified with sodium hydroxide (NaOH) and potassium permanganate (KMnO 4 ) solutions. The CGFs reinforced composites with epoxy matrix were fabricated with the aid of compression molding technique and the samples were subjected to wear tests. The effect of fiber surface modification over the tribological characteristics of these composites such as frictional force, coefficient of friction, and rate of wear was evaluated by varying the time of wear from 40 to 1040 s at an interval of 40 s. From the results, it is found that the weight loss varies between 0.0013 and 0.0018g. Scanning electron microscopy studies are also carried out to observe the surfaces of the samples before and after wear tests. Experimental results portrayed that NaOH treated CGF composites rendered better tribological behavior when compared with untreated and KMnO 4 treated CGF composites.
