Study of Some Properties for Cold-Curing Acrylic Resin Reienforced With Nano Yttrium Oxide

Abstract

Through the last two to three dictate, composite materials had being applied enormously inmany industry fields. This is as fact that this type of materials possess; high strength toweight ratio, high stiffness, and limit thermal conductivity. In this work Nano-Yttrium oxidewith (0%, 1%, 2%, 3% and 4%) weight fraction had been added, as reinforcement phase, toacrylic resin (cold curing). Various physical and mechanical tests had done for determiningthe development in the properties of the prepared composite samples like: hardness, tensilestrength, thermal conductivity, water absorption and density. The results show: decreasingtensile strength with increasing Nano-Y2O3 weight fraction, maximum decline in tensilestrength was at (4) % Y2O3, about (16.2) % of Acrylic strength; increasing in hardness withincreasing Nano-Y2O3 weight fraction, maximum hardness was at (4) % Y2O3, about (107)% of Acrylic hardness, no obviously density change with increasing Nano-Y2O3 weightfraction, decreasing water adsorption with increasing Nano-Y2O3 weight fraction, maximumdecreasing in water absorption percentage was at (4) % of Y2O3, about (93) % of Acrylicwater absorption, decreasing thermal conductivity with increasing weight fractions of Nano-Y2O3, maximum decline in thermal conductivity was at (4)% of Y2O3 , about (90)% ofAcrylic thermal conductivity
