Abstract

To improve the thermal performance of phase change materials (PCMs), graphite nanofibers were embedded into a paraffin PCM. The thermal effects of graphite fiber loading levels (0-5 wt %) and graphite fiber type (herringbone, ribbon, or platelet) during the melting process were examined for a 131 cm³ volume system with power loads between 3 W and 7 W (1160-2710 W/m²). It was found that the maximum system temperature decreased as graphite fiber loading levels increased and that the results were fiber-structure dependent.
