The Use of Pomegranate Shell Residues to Reinforcement the PMMA Used in Dentures

Abstract

Polymethyl methacrylate (PMMA) resin was used in this research with pomegranate peel particles in weight fractions ((0,5,10,15,20,25,30% as a reinforcement material with a granular size of 45µm)). The samples were subjected to mechanical tests to study some mechanical properties (hardness, tensile, compressive) at laboratory temperature (27°C). The results of mechanical tests represented by (tensile, compressive) showed that the best value obtained for the tensile modulus is (68Mpa) at a mass fraction of 15%, and the best value for compressive strength (93 Mpa) at a mass fraction of 10%, while the hardness values reach the lowest value (70N/mm2 due to the increased reinforcement with pomegranate peels).
