Nowadays, implant material become an attractive attention for the researchers to look for alternative materials that better than the previous material. Several complaints have been found due to the use of titanium and steel as implants in the knee. Composite is the main option and being the center of attention and nanomaterials are a promising new breakthroughs. This study offers a new solution for the knee implant in the form of ZnO-Al2O3 nanocomposite as knee implant material. Before being applied to the world of orthopedics, the nanocomposite has been tested using a mechanical testing using hydraulic press machine and has done the compressive strength and shear simulated using software simulation with Catia Version 5 Release 17 (V5R17) and ANSYS. The results of the compressive strength of composites with different percentage comparisons showed that 50% ZnO and 50% Al2O3 has the highest compressive strength compared to other composition ratio (80-20 and 65-35). Based on simulation data, ZnO-Al2O3 nanocomposite has the highest strength on the composition ratio of 50% ZnO and 50% Al2O3 which has the ability to withstand a compressive stress of 3 GPa, equivalent to 300 x 107 N/m2. © 2006-2016 Asian Research Publishing Network (ARPN).
