Abstract

The friction and wear of polyethylene matrix composites reinforced by unidirectional continuous copper wires are discussed in this work.
 
On the basis of experimental results, it was found that friction coefficient displayed by the scratch of PE reinforced by copper wires decreased with increasing number of wires. As the load increased friction coefficient increased. It seems that the presence of metallic wires decreased the hardness of the polymeric materials so that the material removal by the indenter was easier. Wire diameter had insignificant effect on friction coefficient.
 
Copper wires reinforcing PE experienced decreasing wear trend with increasing number of wires. Normal load showed significant effect on wear of PE, where the variations were more pronounced.The decrease in friction coefficient and wear may be attributed to the fact that, the copper wires as good heat conductor transferred heat during molding out of the polymeric materials. This process increased the rate of cooling causing softening of the matrix. This effect is considered as result of crystal phase change in the structure, where the elastic part of polymer viscoelasticity decreased causing significant decrease in the microhardness of the tested polymeric materials.
