The purpose of this study was to construct and eva‎luate the mechanical properties of UHMWPE composite according to the mechanical properties using forsterite and carbon nanotubes in bone implants and the effect of adding 15% by weight of forsterite and unbearable 0.025, 0.05. And 0.075 percentage of carbon nanotubes were investigated for the mechanical properties of the final composite. In this regard, Forsterite powder was prepared using sol-gel method and its properties were investigated using XRD and STA tests. According to the results, the synthesized forsterite had a high purity and a particle size of 39 nm. Then, in order to prepare the composite powder, the materials were mixed by mixing in liquid phase and sonication in vitamin E method. Then, to make the final composite powder, the melt mixing method was used using an internal mixer. In order to investigate the mechanical properties, tensile, nano-indentation and nano-scratch tests were performed on the samples and the failure level of the samples was examined using a scanning electron microscope (SEM). SEM images and DS results showed good production of E-test particles in the composite. The sample with 0.05% carbon nanotube is specified as the optimal value in the composite and the samples in the tensile test compared to the composite have 50% of their strength, which are composite samples made by this method.
