Current work is aimed to preparation the nanocomposites laminatesof low density and good durability to use in structural applications. So, in thispaper, the preparation and compare of some mechanical properties of twogroups of tri-polymer blends composites consisting of ((93% unsaturatedpolyester resin (UP)+(5%PMMA) (Poly methyl methacrylate)+2%NR(Natural Rubber)) as the matrix materials. Added the reinforce materials(silica (SiO2) and zirconia (ZrO2) nanoparticles) individually, with differentvolume fraction of (0, 0.5, 1, 1.5%) to the ternary polymer blends accordingto the following formula:- [((100-X) (93%UP)+2%NR+5%PMMA): (X%SiO2or X% ZrO2)] The first group is composed of matrix material reinforced withzirconia (ZrO2) nanoparticles with average diameter of nanoparticles(56.88nm) and the second group is composed of matrix material reinforcedwith silica (SiO2) nanoparticles with average diameter of nanoparticles(24.59nm). Then used as a matrix material for the preparation of hybridlaminar composites materials, reinforcement with one and two layers ofwoven carbon fibers The research included the study of the influence ofvolume fraction of nanoparticles on some of mechanical and physicalproperties like flexural strength, flexural modulus impact strength, and impactfracture toughness, in addition to test infrared spectroscopy (FTIR) and all ofthese tests were carried out at laboratory temperature. Search results haveshown that the values of (flexural modulus and impact strength and fracturetoughness) increases with the increase of the nanoparticles ratios in polymerblend nano composite of prepared samples. While flexural strength valuedecreases with the increase in the volume fraction of nanoparticles in polymerblend nano composite. The fracture energy of the of hybrid laminarcomposites is higher than those containing only the nanoparticles powders.Morphology test by scanning electron microscope indicates that a goodadhesion or interfacial interactions between the Nano powders particles,carbon fibers and components of ternary polymer blend. Which results inhigher the carbon fibers efficiency factor, and hence higher mechanicalstrength. So, the hybrid laminar nano composites, which appear high flexuralmodulus and impact strength and fracture toughness, can be foreseen toprovide valuable contribution to high performance structural applications.

Poly methyl methacrylate (PMMA), widely used as a prosthodontic denture base, the denture base materials should exhibit good mechanical properties and dimensional stability in moist environment. In the present research, efforts are made to develop the properties of PMMA resin that used for upper and lower prosthesis complete denture, by addition four different types of nanoparticles, which are fly ash, fly dust, zirconia and aluminum that added with different ratios of volume fractions of (1%, 2% and 3%) to poly methyl methacrylate (PMMA), cold cured resin (castavaria) is the new fluid resin (pour type) as a matrix. In this work, the Nano composite and hybrid Nano composite for prosthetic dentures specimens, preparation was done by using (Hand Lay-Up) method as six groups which includes: the first three groups consists of PMMA resin reinforced by fly ash , fly dust and ZrO2 nanoparticles respectively, the second three groups consists of three types of hybrid Nano composites, which includes ((PMMA: X% nF.A)+ (1%Al + 3% ZrO2)), ((PMMA: X% nD.A)+ (1%Al + 3% ZrO2)) and ((PMMA - X%nZrO2)+(1%F.A + 3%F.D)) respectively. The hardness and flexural tests results show that the values of the hardness, flexural strength, Maximum shear stress and flexural modules increased and with the addition of Nano powders (fly ash, fly dust, zirconia, and aluminum). And the results showed that the maximum values of hardness reach to (84.166) for ((PMMA: 3%nZrO2) + (1%F.A + 3%F.D)) hybrid Nano composite, whereas the maximum values of hardness for Nano composite reach to (83.333) for (PMMA: 3%nZrO2) Nano composite. Also, the results showed that the maximum values of flexural strength and Maximum shear stress reaches to (101MPa) and (2.4738MPa) respectively for (PMMA: 2%nF.D) Nano composite. Moreover, the results showed that the maximum values of flexural modules reaches to (13.95GPa) for ((PMMA: 3% nF.A) + (1%Al + 3%ZrO2)) hybrid Nano composite, whereas the maximum values of flexural modules for Nano composite reach to (12GPa) for (PMMA-3%nZrO2) Nano composite.
