Abstract
The friction and wear of polyethylene (PE) matrix composites reinforced by unidirectional continuous steel wires of different diameters are discussed in this work. On the basis of experimental results, it was observed that friction coefficient displayed by the scratch of PE reinforced by steel wires showed that as the load increased friction coefficient increased due to the increased material removed during scratch. Besides, drastic decrease in friction coefficient was observed with increasing number of wires. It was observed that as the diameter of the steel wire increased, the values of the friction coefficient decreased due to the increase of the rate of cooling as result of the increased cross section area. The increase of the number and diameter of the steel wires reinforcing PE caused significant wear decrease. Wear significantly increased with increasing normal load. Wear values were influenced by the variation of steel wire diameter due to the variation of the cooling rate.
