Abstract Hexagonal boron nitride/SiO 2 /glass fiber mixtures were calcined at 650 and 850°C and the resulting materials were used to improve the through‐plane thermal conductivity of a polypropylene (PP) composite. The mixtures were characterized using Fourier transmission infrared spectroscopy, X‐ray photoelectron spectroscopy, and scanning electron microscopy. At 850°C, the glass fiber surface was largely covered by hexagonal boron nitride. A significant improvement of through‐plane thermal conductivity of PP composite was observed after the addition of hexagonal boron nitride/SiO 2 /glass fiber calcined at 850°C. Calcination temperature and the presence of glass fiber strongly affected the through‐plane thermal conductivity of the composite.
