“…Many researchers have investigated the temprature on the wear and frictional behaviour of polymers. For instance, Tahir et al [9] studied the effect of the operating temperature on the tribological behaviour of carbon fibre composites with a different epoxy system. They reported that the temperature has a high influence on the COF behaviour, and a drastic increase in the COF was reported at 90 ℃, below the glass transition temperature (Tg) of the epoxy, 100 ℃ [31].…”

“…Unlike metals, the wear performance of polymers is very sensitive to the operating temperature, i.e., the induced heat at the contact zone during the wear process. In tribological applications of polymers, one main parameter to be considered during the wear process is how the generated heat of the rubbing process affects the tribological components' mechanical and wear performances [9][10][11]. Interface temperature may deteriorate these components' mechanical properties by reducing the hardness and the stiffness, and it can break the polymer bonds, resulting in a higher wear rate and a higher coefficient of friction (COF) for components [9,12].…”

Epoxy resin is one of the most widely used thermoset polymers in high-performance composite materials for lightweight applications. However, epoxy has a high coefficient of friction, which limits its tribological applications. In this study, the effect was investigated of different weight fractions of solid lubricant graphene nanoplatelets (GNPs), ranging from 0 to 4.5 wt%, on mechanical and adhesive wear performance of epoxy. Adhesive wear tests covered mild and severe wear regimes. The correlation of tribological and mechanical properties was studied as well. Scanning electron microscopy (SEM) was used to observe the failure mechanisms for both tribological and mechanical samples after each test. The results revealed that the addition of GNPs to the epoxy improved its stiffness and hardness but reduced its fracture strength and toughness. Adhesive wear performance exhibited high efficiency with GNP additions and showed reductions in the specific wear rate, the coefficient of friction, and the induced interface temperature by 76%, 37%, and 22%, respectively. A fatigue wear mechanism was predominant as the applied load increased. Most importantly, severe wear signs occurred when the interface temperature reached the heat distortion temperature of the epoxy. The tribological, and mechanical properties showed only a weak correlation to each other. The addition of GNPs to epoxy by less than 4.5 wt% was highly efficient to improve the wear performance while maintaining the fracture strength and toughness. Fourier transform infrared spectroscopy (FTIR) analysis shows no chemical interaction between the epoxy matrix with GNPs, which implies its physical interaction.

“…Pertaining to the previous study by Kaggwa et al 23) , activated carbon in nanofluid has significantly increased the lubricant viscosity and improved the heat transfer efficiency. Furthermore, Ayuma et al 24) found that the activated carbon generated a tribofilm between two contact surfaces thus prevented wear and friction during the pin-on-disc test. The carbon-based tribofilm adhered at the contact surfaces which prohibited the adhesion to occur.…”

Nonedible vegetable-based oil was recently explored due to the demand for a sustainable element in a machining process. The aim of this study is to critically analyse the tribological performance of nanofluid from nonedible (modified jatropha oil, MJO) nanofluid added with activated carbon nanoparticles. The tribology test was conducted through four-ball test using various concentration ratios of nanoparticles. According to the findings, MJOa2 (0.025wt.% activated carbon in MJO) showed the lowest coefficient of friction and mean wear scar diameter, produced a smoother surface with low surface roughness value, followed by MJOa3 (0.05wt.% activated carbon in MJO), MJOa1 (0.01wt.% activated carbon in MJO) and synthetic ester (SE). Therefore, MJOa2 was considerably suitable for metalworking fluid application which emphasizing the element of sustainability.

“…There are still few studies on natural fiber as a friction material. Some research has been conducted using the powdered form of natural fiber (sugarcane fiber [13], banana peel [14], palm kernel [15], and periwinkle cells [16]) for friction material. This article discusses the development of cantala fiber in the form of short fibers as the reinforcement material for the friction brake composite.…”

Friction brake materials are made from a mixture of materials with different properties in order to meet the brake performance requirement. Friction brake material contains a reinforcement fiber that serves to maintain the integrity of the material when subjected to loading. Natural fiber has the potential to be used as a reinforcement material for friction material due to some of its superior characteristics. In this research, friction brake materials using cantala fibers were developed to investigate their frictional characteristics. The volume fraction of the cantala fibers in the specimens was varied from 0%, 4%, 8%, to 12% of the total composition of the friction brake material. The manufacturing of the specimen was initiated by mixing the ingredients, followed by cold pressing of the mixture, hot pressing of the preform, and finally post-curing of the specimens. The frictional characteristics of the specimens were evaluated using pin-on-disc tribometer. The result showed that the cantala fibers contributed to the decrease in the coefficient of friction. An increase in contact pressure caused the coefficient of friction to increase, while the increase in sliding speed caused a decrease in the coefficient of friction. The addition of cantala fiber into the composite could increase wear resistance and stabilize the coefficient of friction of the friction brake material.
