EPOXY RESINS REINFORCED WITH BORON NITRIDE AND ALUMINUM OXIDE PARTICLES: A NUMERICAL THERMAL CONDUCTIVITY ANALYSIS

Abstract

An epoxy composite containing boron nitride (BN) and Al2O3 micro-fillers implanted was tested for heat conductivity in this thesis. The thermal conductivities of these composites, which had BN-Al2O3 contents varying from 0% to 50% volume were numerically derived from simulation using the CAE programme ANSYS modeled using representative volume elements, which explains heat transmission inside epoxy matrix filled with micro-BNs and Al2O3. There is an increase in effective thermal conductivity of almost as high as 7-8 times for 50% volume percent BN-Al2O3 in epoxy matrix compared to plain epoxy resin. The experimental data on similar filler type and concentrations exhibit similar trends.
