This document summarizes research on enhancing the thermal conductivity of epoxy matrix composites by filling them with boron nitride (BN) particles. The researchers prepared epoxy composites with BN content ranging from 0-11.3% by volume and measured their thermal conductivities experimentally. They also used finite element analysis to model heat transfer in the composites and validate the simulated effective thermal conductivities. Their results showed that an 11.3% BN filling increased thermal conductivity by 27.82% while a 30% filling increased it by 440%, demonstrating BN's ability to significantly improve an epoxy matrix's heat dissipation capabilities.
