Abstract

The main objective of this work is to investigate the influence of multi-walled carbon nanotubes (MWCNTs) on the hardness and wear of polymethyl methacrylate (PMMA) reinforced by MWCNTs of 0.1, 0.2, 0.3, 0.4 and 0.5 wt. % contents. PMMA is prepared at both hot and cold acrylic resins to be used as denture base materials. The hardness of the proposed composites is measured by Shore D Durometer on the surface and side of the composites. Wear of MWCNTs/PMMA composites is measured by weighing the specimens before and after the test on a reciprocating wear tester.
 
Based on the experiments, it is observed that the hardness of hot cured composites increased while wear decreased by increasing MWCNTs content unlike the cold cured composites,. In addition to that, it is shown that wear of hot cured composites decreased by increasing normal loads also unlike cold cured composites where wear increased by increasing normal loads. From this study, it can be concluded that hot cured composites are better than cold cured composites as denture base materials.
