Abstract

The present work investigates the influence of the addition of nanoparticles to epoxy on the tribological properties, such as friction coefficient and wear resistance. The nanoparticles such as carbon (C) and aluminum oxide (Al2O3), as well as microparticles of bronze (Bz) and aluminum (Al) of 1, 2, 3 and 4 wt. % content are added to epoxy matrix.
 
Based on the experimental results, it was found that increasing filling materials content caused friction coefficient increase. Besides, as the load increased, friction coefficient increased. This behavior is attributed to the increase of contact area due to the increase of the depth of insert in the matrix of the tested composites. Bz and Al particles show the lowest values of friction coefficient compared to Al2O3 and C particles because of their ductility and lubricity. Also it is observed that as the filling material increased the wear decreased. This behavior is attributed to the increase of wear resistance of composites. In addition, it seems that both C nanoparticles and Bz particles work as solid lubricants where the insert would be less abrasive.
