摘要

Finite element models of the porous structure of hydroxyapatite composite ceramics reinforced with multi-walled carbon nanotubes are developed and their mechanical characteristics are determined numerically using the finite element procedure. The effect of porosity and nanotube additives on the Vickers microhardness, compressive strength, and flexural strength of the model samples is investigated. It is shown that porosity and nanotube reinforcement have comparable effects on mechanical properties, which opens prospects for designing purpose-tailored biocomposites.
