This study describes the preparation and study of the properties of Nano composite particles prepared in a sol-gel method which consists of two materials (Αl2Ο3-MgΟ). The powder was evaluated by x-ray diffraction analysis, scanning electron microscopy analysis (SEM), particle size analysis, and energy dispersive x-ray analysis (EDX) and antibacterial test. The evaluation results of the nanocomposite particles shows a good distribution of the chemical composition between aluminum oxide and magnesium oxide, smoothness in particles size where it reached to (54.9, 59.8) nm at calcination in (550 0C and 850 0C) respectively, formation of different shapes of nanoparticles and different phases of the Αl2Ο3 particles (kappa and gamma) and nanopowder have well antibacterial action, Therefore, this reflects the efficiency of the proposed method to manufacture the nanocomposite powder and the possibility of using this powder as a strengthening material for the composite materials and using these composite materials in bio applications, especially in the fabrication of artificial limbs.
The goal of modern industries is to use low-cost and environmentally friendly materials, whether natural or industrial, especially for engineering and medical applications. The present work includes the manufacture of a composite material of lamination resin reinforced with two types of particles, an organic type (animal horn particles and bamboo particles) and the second type inorganic (zinc oxide particles), according to the selected weight ratios (2,4,6, and 8) %wt. and all the particles were at a granular size (5 µm). The organic particles were prepared manually according to special steps to obtain the best results. The prepared particles were checked manually by examining the particulate size by the vibrating sieve and the shape of the particles through the (SEM) test. As for the mechanical behavior of the composite material, it was studied through (tensile, shock, and hardness) tests. The results of the examination showed that the best addition of particulate matter was for the inorganic particles (zinc oxide) and all tests if compared to the organic particles. The best ratio of zinc oxide particles is (6%wt.) as the results of the tensile, shock, and hardness tests were (59 Mpa, 4.4 J, and 95) respectively. Therefore, this ratio is suitable for use in various engineering and medical applications such as foot prosthetics.
