Abstract:
This research investigates the radiological protection properties of composite materials comprising aramid and linen fabrics integrated within an epoxy matrix through advanced computational simulations. The study focuses on assessing the efficacy of these composites in attenuating gamma radiation, with specific emphasis on measuring the photon flux between layers and the energy deposition within the material structure. Utilizing Monte Carlo simulation techniques, the interaction of gamma photons with the composite layers was modeled, accounting for variations in layer thickness, material density, and stacking configurations. The simulations provide detailed data on the attenuation coefficients and energy absorption profiles, enabling a comprehensive evaluation of the shielding performance. The choice of aramid and linen fabrics, combined with the epoxy matrix, aims to balance lightweight and flexible characteristics with robust radiation protection, offering potential applications in medical imaging, aerospace radiation shielding, and industrial safety equipment. Preliminary results indicate that the hybrid composite structure exhibits promising attenuation capabilities, with the layering sequence and material composition significantly influencing the reduction of photon flux and energy deposition. These findings contribute to the development of sustainable, high-performance radiological protection materials, paving the way for further experimental validation and optimization of composite designs for real-world applications.
