Effect of Nano (Y2O3 ) on the Mechanical Properties of the (PS:NR:PMMA) Polymer Blend Composite

Study of the mechanical properties of polymer blend composite to the preparation of matrix Unsaturated Polyester resin (UPS) with natural rubber (NR) and polymethyl methacrylate (UPS:NR:PMMA) material and study influence Nano Yttrium Oxide (Y2O3) on the composite . The first group is the preparation of samples of the mixture of polyester matrix with natural rubber material in ratio certain, It was examined the mechanical properties: tensile, flexure at break, young modules, hardness and compression decreases with increases the natural Rubber ratio but Elongation test increases when increases Rubber ratio. The second group is the samples preparation of the mixture of polyester with PMMA material, test mechanical properties decreases with increases the PMMA ratio. Third group was prepared from a mixture of polymer blend composite, which consists of fixed ratios of polyester, natural rubber and PMMA. Addition of Nano material Y2O3 at ratio (0.25-1.5) wt% .result test mechanical properties increases with increases the Y2O3 ratio.
