Abstract

The paper presents the results of studies of thermal conductivity, structure and physico-chemical properties of samples of polymer composite material based on thermosetting phenol-formaldehyde resin and hexagonal boron nitride. It was found that with an increase in the volume fraction of boron nitride from 5 to 85%, the effective thermal conductivity coefficient at 300 K increased from 0.63 to 18.5 W/m·K. The experimental results are compared with the data calculated using known theoretical models used to describe the process of thermal conductivity in polymer composite materials.
