This study for the first time evaluated quantitatively the effect of carbon nanofibre (CNF) reinforcement on tribological properties of epoxy nanocomposites. Nanocomposites containing 0.0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 wt% CNF were fabricated by casting technique after dispersing CNFs in epoxy resin by ultrasonication and mechanical stirring. Sliding and abrasive wear were investigated using a pin-on-disc apparatus and evaluated statistically for the effect of CNF reinforcement by one-way ANOVA. Sliding wear test revealed that CNF content significantly affected specific wear rate but not frictional coefficient. Reinforcement with 0.5 to 2.5 wt% CNF reduced the specific wear rate compared to the control (neat epoxy). However, specific wear rate was increased at 3.0 wt% CNF. Abrasive wear test showed that CNF reinforcement causes numerical decrease in wear rate but the effect was statistically non-significant. Surface morphology was investigated by SEM to obtain the possible wear mechanism of the nanocomposites.

Epoxy alumina composite was fabricated by instant cross-linking process containing 0.5, 1.0 and 1.5 wt.% of alumina reinforcement. Ultrasonication process is used to disperse alumina nanoparticles in epoxy. To study effect of particle morphology two types of alumina nanoparticle’s were used, one was of rod shape whose diameter varies from 5–10 nm and length not more than 50 nm. Whereas other type of particle used was spherical in shape with diameter varying from 27-43 nm. Reinforcement of alumina nano particles enhances the micro hardness of epoxy composite. There is no significant effect of reinforcement on water absorption behavior of epoxy composite. Friction and dry sliding wear behavior was experimentally evaluated by pin on disc setup. Infusion of alumina nanoparticles improves friction and wear behavior of epoxy composite. Reduction of 34% in friction coefficient (CoF) was recorded at 1.5 wt.% of spherical alumina particles. Wear rate also decreases with by 74% at 1.0 wt.% inclusion of spherical nano particles. Calculated energy dissipation was in good correlation with wear rate, thus a good method to predict the wear characteristics of epoxy composite. Stable development of tribo-film and surface smoothening are the major phenomena in improvement of tribological behavior of epoxy composite.
