PREPARATION AND MODELLING OF COMPOSITE MATERIALS (POLYESTER-ALUMINA) AS IMPLANT IN HUMAN BODY

Due to spreading the composite materials in different life areas, there have been many researches dealing with composite materials. This research aims to study the possibility of manufacturing materials composite particles of Unsaturated Polyester reinforced by ceramic particles of Alumina. Unsaturated polyester resin used widely in different industries because of good mechanical and physical properties such as stability of dimensions, the ability of interaction as well easy to forming and low cost. In this research the effect of adding Alumina as a strength phase to unsaturated polyester resin has studied, in this study the unsaturated polyester resin strengthen with different percentage (2.5, 5, 10)% from Alumina has been executed and then the mechanical behaviour of prepare samples has been studied. The tests include (bending, density, water absorption, hardness and Modelling ANSYS) and the results show that composite materials have less density al 10% Al2O3 which is decreased by 6%and largest result for bending which is 60% and also less water absorbing which is 0.6%. On the other hands adding Al2O3 in any ratio (2.5, 5, 10)% increase the hardness of unsaturated polyester resin as well as reduction the strain as shown in ANSYS Modelling.
