Study of some properties for cold-curing acrylic resin reienforced with nano yttrium oxide

الملخص EN

Through the last two to three dictate, composite materials had being applied enormously in many industry fields.

This is as fact that this type of materials possess; high strength to weight ratio, high stiffness, and limit thermal conductivity.

In this work Nano-Yttrium oxide with (0%, 1%, 2%, 3% and 4%) weight fraction had been added, as reinforcement phase, to acrylic resin (cold curing).

Various physical and mechanical tests had done for determining the development in the properties of the prepared composite samples like: hardness, tensile strength, thermal conductivity, water absorption and density.

The results show: decreasing tensile strength with increasing Nano-Y2O3 weight fraction, maximum decline in tensile strength was at (4) % Y2O3, about (16.2) % of Acrylic strength; increasing in hardness with increasing Nano-Y2O3 weight fraction, maximum hardness was at (4) % Y2O3, about (107) % of Acrylic hardness, no obviously density change with increasing Nano-Y2O3 weight fraction, decreasing water adsorption with increasing Nano-Y2O3 weight fraction, maximum decreasing in water absorption percentage was at (4) % of Y2O3, about (93) % of Acrylic water absorption, decreasing thermal conductivity with increasing weight fractions of NanoY2O3, maximum decline in thermal conductivity was at (4)% of Y2O3 , about (90)% of Acrylic thermal conductivity
