The Thermal Properties And Mechanical Behavior Of Xlpe/Al2O3 Nanocomposites

Abstract

This study investigates the thermal and mechanical properties of cross-linked polyethylene (XLPE) reinforced with aluminum oxide (Al₂O₃) nanoparticles to evaluate its potential for enhanced performance in industrial applications. The addition of Al₂O₃ nanoparticles to XLPE aims to improve its thermal stability, mechanical strength, and resistance to degradation. Nanocomposites with varying Al₂O₃ loadings were prepared and subjected to thermal and mechanical testing. Thermal properties, including thermal conductivity and heat resistance, were measured, revealing that the inclusion of Al₂O₃ nanoparticles increases thermal stability due to better heat dissipation. Mechanical tests, including tensile and impact strength assessments, showed that the nanocomposites exhibit improved strength and rigidity relative to pure XLPE. These enhancements are attributed to the efficient stress transfer at the nanoparticle-matrix interface. The findings suggest that XLPE/Al₂O₃ nanocomposites offer a promising approach for applications requiring superior thermal and mechanical performance, particularly in high-stress or high-temperature environments.
