Elastic Properties Investigation on Random and Ordered ZrO2 Nanotube-Reinforced HA and β-TCP Biocomposites with Finite Element Approach

The elastic properties of random and ordered ZrO2 nanotube- (ZrNT-) reinforced HA and β-TCP biocomposites were carried out by a numerical investigation with finite element approach. The elastic modulus, shear modulus, and Poisson’s ratio affected by various ZrNT volume fractions (5.0？vol.%, 5.5？vol.%, 6.5？vol.%, 7.5？vol.%, 8.5？vol.%, and 10.0？vol.%) and aspect ratios (3, 5, 10 and 20) for both random and ordered reinforced composites were obtained and analysed. The advantages of random and ordered reinforced composites were further discussed. The random reinforced composite is suggested to be a proper candidate for ZrO2 nanotube-reinforced biocomposite on the application of bone repair and the substitute
