This research aims to study the addition of nanoclays on unsaturated polyester (UP) and epoxy resin (EP) as filling and by weight percentage (2%, 4% and 6%) to this mixture and then study the extent of the effect of this addition on wear rate of the composites’ material where three loads were adopted (10, 15 and 20[Formula: see text]N), respectively, on the iron hard disk (269 HB) and copper hard disk of 111[Formula: see text]HB for the resin before and after adding the clays, where the approved sliding velocities were 4.1887, 3.1415 and 2.0943[Formula: see text]m/sec, respectively, and the test duration was 10 min on the test disc. Immersion of samples in the water for 2, 4, 6 and 8 weeks showed a clear improvement in the wear rate and tear values of dry and submerged conditions in a water under different conditions of load change, slipping speed, time and temperature stability after adding the nanoclays to the polymer.
