Harnessing Fe 2 O 3 to Improve HAP Composites: Investigating Radiation Shielding, Mechanical Attributes, and Magnetic Field Effects

Abstract

Hydroxyapatite (HAP) bio-composites are widely utilized for the repair and replacement of bone and teeth tissues in humans. However, due to their suboptimal mechanical properties, the strength and durability of pure HAP have been improved by incorporating various alloys and materials. This study examines the radiation shielding and mechanical properties of Fe2O3-reinforced HAP composites for use as implants, with Fe2O3 concentrations of 0.0, 2.5, 5.0, and 7.5 wt.%. The study also investigates the composite's behavior in a magnetic field. Using the FLUKA Monte Carlo Code, radiation shielding factors are determined, and the mechanical properties of the composites are assessed through theoretical methods. Results indicate that increasing Fe2O3 content in HAP bio-composites enhances the radiation shielding and mechanical properties of the selected samples. Additionally, without a magnetic field, particle distribution displays symmetry along the x-axis; however, when exposed to a magnetic field of Bx=5 microT, a distinct pattern emerges.
