The effects of using different fillers and the effects of filler content and particle size on the thermal properties of thermal interface materials were investigated. The most prominent enhancement in thermal conductivity was observed for samples containing carbon nanotubes and graphite. The filler particle size was also found to significantly affect the thermal conductivity, as smaller fillers resulted in a higher thermal conductivity. The article also describes two sample holders ...
In the soft tooling process for making moulds, polyurethane is often used as a flexible mould material. The low thermal conductivity of polyurethane results in a long solidification time of the wax/plastic pattern produced in the soft tooling process. In an effort to address this issue, the authors of this article have added highly conductive fillers to polyurethane. The fillers used for this study were aluminum fine powder and ...
Graphite nanoplatelets were dispersed in varying quantities into a silicone matrix to form composite materials with higher thermal conductivities than the pure silicone matrix without sacrificing mechanical properties. It was found that the thermal conductivities of the composites increased with increasing GNP content as well as with increasing GNP particle size. The composites were found to be effectively electrically insulating, and it was found that the addition of GNP did ...
This article is a literature review of research that has been done on the thermal conductivity of cast iron. The article outlines the effects of graphite additives, alloying elements, matrix, and temperature on the thermal conductivity. Numerical models that have been developed are also discussed in the review....
Graphite nano-platelets (GnPs) were dispersed in polyethylene glycol (PEG)/polymethyl methacrylate (PMMA) to form a PEG/PMMA/GnPs composite organic form-stable phase change material. The effects of the incorporation of the GnPs on the morphological, structural, thermal, and electrical properties of the composite were then assessed. The experimental results indicated that the incorporation of the GnPs into the polymer increased the thermal and electrical conductivities, and it was concluded that ...
