Abstract:

The main objective of this experimental approach is to find out effect of boron carbide contents on shielding properties of composite material. The
Formulation of Styrene Butadiene Rubber composites have been prepared by using Boron Carbide contents, ranging from 5% to 25%. These composites have been subjected to various tests and experiments have been conducted to study thermal neutron shielding properties of these composites by neutron irradiation. Moreover, linear attenuation coefficient has been calculated from this data. Monte Carlo N-Particle transport code simulations have been used to compare the simulated results to experimental results. Mechanical properties such as hardness, swelling uptake studies, and thermal gravimetric analysis have been carried out, and it is observed that hardness increased 5% and swelling index values, specifically lower for water, decreased by increasing boron carbide contents. For thermal neutron shielding properties, graphs show the slope of composite with higher concentration of boron carbide is steeper than the one with lower amount of boron. Furthermore, both the experimentally calculated and MCNP estimated values are in good agreement. These results suggested that shielding capability of composites increases with the boron carbide amount. More the boron carbide content, less thickness of composite will serve the purpose of shielding.
