Abstract: Adding metallic nanoparticles to a conventional fluid increases the thermal conductivity of the solution. In this study, flaked boron nitride (BN) and high-aspect-ratio multi-walled carbon nanotubes (MWCNTs) were added to epoxy composites to increase thermal conductivity. A thermal analyser measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that adding a small volume of MWCNT to the epoxy composite significantly improved thermal conductivity compared to when pristine CNTs were used. It was also noted that the thermal conductivity of the composite increased with concentration of BN.
