Investigation of Physical Properties of Polymeric Nanocomposite Material Used in Structural Applications

Abstract

In the current research were prepared composite materials, from thermoplastic polymer (PMMA) as a matrix materials by used the hand lay-out technique. The composite material was prepared from two sets of composites materials the first set consists of a poly methyl Methacrylate (PMMA) resin as matrix material reinforced by nanoparticle of aluminum Oxide (Al2O3) with average size (53.60) nm once and the second group is composed of poly methyl Methacrylate resin reinforced by nanoparticle of Magnesium Oxide (MgO) with average size (52.54) nm. The research includes the study of the influence of the selected volumetric fraction ratios of (0.5, 1, 1.5%) for the reinforce materials, on the properties of the prepared composite materials. Number of physical tests which included (density, Thermal Conductivity, specific heat and thermal diffusivity, and DSC) . which all test were done at room temperature. Result of the work shows that the values of Thermal Conductivity, Specific Gravity, Tg and Tm) increase with the increase of volume fraction of nanoparticle for both groups of polymeric Nano composites material. Whereas decreased the specific heat values with the increase of volume fraction of nanoparticle for both groups of polymeric Nano composites material Moreover the poly methyl Methacrylate Nano composite material reinforced with nanoparticle of aluminum Oxide possesses physical properties higher than those of Article composites reinforced with nanoparticle of Magnesium Oxide
