Abstract: This study reports the preparation of multifunctional hybrid composites based on polypropylene (PP) for potential thermal management applications in automotive. Short carbon fiber (CF) at 5 and 8 wt%, and silane-treated hollow glass microsphere (HGM) at 5, 10, 20, 30, and 40 wt% were incorporated separately in PP along with maleic anhydride-grafted-polypropylene (MA-g-PP). The interplay of filler content and its dispersion and distribution had a significant effect on the thermal conductivity (Kc) of the composites. Highest Kc of 1.20 W/m K was obtained for a CF and HGM wt% of 5 and 20, respectively. The rheological analysis revealed improved flowability as the complex viscosity of composites up to 20 wt% of HGM content was found to be less than PP. The thermal stability improved upon HGM incorporation and the highest thermal stability of ~26°C higher than that for PP was exhibited by hybrid composite with 8 wt% CF and 40 wt% HGM. Furthermore, Nielsen model demonstrated to be the closest fit for the experimental thermal conductivity value of hybrid composites among various micromechanical models used. © 2021 Society of Plastics Engineers
