Effect of Boron Carbide Content on Properties of Thermoplastic Natural Rubber Composite as Thermal Neutron Shielding

Abstract:

In this work, thermoplastic natural rubber (TPNR) composites were produced through melt blending method. Boron carbide (B₄C) as filler was added into the polymer blend (TPNR) with different weight percent from 0% to 30% and the effect of different B₄C contents on mechanical and thermal neutron attenuation properties of TPNR composites has been studied. The phase formation in composites was analyzed using XRD technique. From the results, it showed that the incorporation of B₄C fillers into TPNR matrix has enhanced the macroscopic cross section of the composites, however it lessens the tensile strength. Macroscopic cross section of the composites were increased from 3.34 cm^-1to 14.8 cm^-1, while the tensile strength of the composites decreased from 3.79 MPa to 1.06 MPa with increasing B₄C from 0 wt% to 30 wt%. B₄C diffraction peaks were also increased in intensity with increasing B₄C content.
