Comparing the Mechanical Behavior of Lamination Resin Reinforced with Two Types of Organic and Inorganic Particles Used in Prosthetic Applications

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.
