Abstract:
In the present work, an attempt has been made to study and improve the physical and biomechanical properties of adding Titanium dioxide (TiO۲) and yttria stabilized zirconia (Y-PSZ) Nano fillers ceramic particles for reinforced the high density polyethylene (HDPE) matrix Nanocomposites for fabricated six bio nanocomposites hybrid by using hot pressing technique at different compounding temperature of (۱۸۰,۱۹۰, and ۲۰۰ °C) and compression pressures of (۳۰, ۶۰, and ۹۰ MPa). The fabricated Nano systems were designed, produced and investigated for use in repairs and grafting of the human bones, which are exposed to accidents or life-threatening diseases. The main current research results show that with the increase of the TiO۲ filler contain from ۰ to ۱۰ %, the value bulk densities increase by ۳۰.۲۴ % and when adding ۲% partial stabilized zirconia (Y-PSZ), this value was further increased by ۱۳.۹۱%. For the same conditions the value percentages true porosity decrease by ۴۸.۶۸ % and further by ۸۴.۸۵ %, respectively. For the same previous parametric values, it has also been accessed that the maximum compression strength for this study was increased by ۳۳.۳۴ % and then further by ۲۲ %, where these values higher by ۹۰.۱۱% than the previous mentioned studies. The micro-Vickers Hardness increased by ۳۰.۱۱ % for the second manufacturing system comparing with the first one, while the maximum equivalent von–Misses Stresses obtained from the current work withstand higher stresses than the natural bone by ۵۲.۶۵ higher than the previous studies. The stress safety factors increase by ۵۸.۳۸ % and by ۲۱.۴۲ % for the first and second systems, respectively. The achieved results values for the modeled femur bone is equivalent to actual service of the activity during normal movement of the patient. These results give great the designers choices to use successful bio composites for in vivo tests according to the clinical situation, age and the static and dynamic loads when designing a material to repair the fractured bones due to different types of accidents.
