Investigation of Mechanical and Dry Sliding Wear Behaviours of $AlB_2$/PE Polymer Matrix Composites

In this study, mechanical and wear behaviour of polymer-boride composite ($AlB_2$/PE) materials produced through pressure moulding technique have been experimentally investigated. Three different composite materials that include 5 wt%, 10 wt%, and 20 wt% $AlB_2$ reinforcement phase were tested using pin-on-disk arrangement. Compared with the matrix, the 20 wt% $AlB_2$ composite shows a 71% increase in the ultimate tensile strength and the highest wear resistance.
