November 29. 2017 - The influence of reinforcing epoxy by carbon nanotubes (CNT) and filling by different types of vegetables oils (olive, corn, sunflower, sesame, almond and paraffin oil) on the friction coefficient (µ) and wear resistance is investigated. CNTs of 0.25, 0.5, 0.75 and 1 wt. % content have been added to epoxy matrix mixed by 10 wt. % of vegetable oils. A significant decrease in friction coefficient was observed with increasing CNT content. Oils can be ranked due to their effect in decreasing µ as follows: corn , almond, paraffin, sesame , sunflower and olive oil. On the other hand a significant decrease in wear values were noticed, where sesame oil gives the best wear resistance.
