Enhancement of Wear and Friction Characteristics of Epoxy Resin by Multiwalled Carbon Nanotube and Boron Nitride Nanoparticles

Abstract

Epoxy resin is widely used in engineering applications. However their low thermal stability limits their usage at high sliding velocities and loads. The mechanical properties and thermal stability of a machine element subjected to friction and wear is very important. In this study, friction and tribology behaviors of MWCNT and BN modified epoxy resin have been investigated. Epoxy resin modified by three different nano particle configurations as 0.3% MWCNT, 0.5% BN and 0.5%MWCT/0.3%BN. The tribology characteristics of nano particle modified epoxy resin were compared with properties of neat resin. The friction and tribology behavior of modified epoxy resin were tested at ball-on-disc test stand at 1.2 ms -1 and 1.5 ms -1 sliding velocities under 10 N applied load. The tests were done under dry condition and 1800 m distance. The friction coefficient, wear loss and temperature increase during testing were recorded and compared with that of obtained for neat epoxy. It is observed that nano particle modification was resulted in enhancement in wear resistance and reduction in friction coefficient and working temperatures.

Effects of hexagonal boron nitride based nanofluid on the tribological and performance, emission characteristics of a diesel engine: An experimental study

“…Further, the authors stated that the improvement in load‐carrying and EP ability of lube oil was enhanced due to the dispersion of hBN nanoparticles. The tribological characteristics of epoxy resin were studied by Hayrettin et al 30 using MWCNT and hBN as nanoparticles additive in epoxy resin by using a ball‐on‐disc test. The results revealed that modified epoxy resin has shown improved wear resistance and friction reduction behavior at higher working temperature.…”

Effect of carbon nanotubes on friction and wear of a piston ring and cylinder liner system under dry and lubricated conditions

“…Comparison of the tribological testing results shows that the friction coefficient with CNTs is far less than that without CNTs. We conclude that during dry sliding tests, adding CNTs as a solid lubricant to the PRCL system can greatly decrease friction [26] because CNTs cover the contact surfaces and have sp2 bonding that generates a lower shear force and helps to reduce friction [15,27]. Moreover, a decrease in the friction coefficient can reduce the heat generated during sliding.…”
