In this study, the neutron shielding capabilities of boron carbide (B₄C)-reinforced polyester-matrix composite materials were investigated. For the study, 20- 40- and 60-mm-thick specimens were first prepared by reinforcing with 10–50% B₄C, and later their neutron shielding characteristics were studied by using various characterization techniques. The shielding capability of the composite materials was observed to increase with specimen thickness. In addition, increased amounts of B₄C reinforcement improved the attenuation ratio of the material thereby increasing the shielding effectiveness. This trend, however, changed when the B₄C ratio reached 40% and 50% at which a gradual decrease in neutron attenuation was observed. The experimental setup was also simulated using the Monte Carlo code MCNP-5, and similar computations were carried out. The experimental data almost completely agreed with computational results.

在这项研究中，研究了碳化硼（B ₄ C）增强的聚酯基复合材料的中子屏蔽能力。为了进行研究，首先通过用10％至5​​0％的B ₄ C增强来制备20至40和60毫米厚的标本，然后使用各种表征技术研究其中子屏蔽特性。观察到复合材料的屏蔽能力随样品厚度的增加而增加。另外，增加的B ₄ C增强量改善了材料的衰减率，从而提高了屏蔽效果。但是，当B ₄C比率达到40％和50％，此时观察到中子衰减逐渐降低。还使用蒙特卡罗代码MCNP-5对实验装置进行了仿真，并进行了类似的计算。实验数据几乎完全与计算结果一致。
