This study proposes polymeric dies capable of producing aluminum sheets that will withstand wear and compressive stresses. The wear behavior and compressive strength of the proposed epoxy matrix composites filled by aluminum oxide (Al2O3) nanoparticles and paraffin oil is discussed in this study. Six reinforced dies were produced with different volume fractions containing aluminum oxide nanoparticles (0, 0.2, 0.4, 0.6, 0.8 and 1.0 %), then another set of dies were fabricated with the same volume fractions and 3.5 wt. % paraffin oil content. An optical microscope test was carried out to measure dimensional variation caused by wear. It was found that adding paraffin oil to epoxy filled by 0.2 wt. % aluminum oxide has reduced wear of the corners of dies.
