Silicone materials have high electrical and thermal insulation properties that are useful for engineering applications. In this study, vapour grown carbon nanofibers (VGCNF) were produced by two different methods and were added to silicone rubber to improve conductivity. A thermal constant analyser measured the thermal conductivities of the silicone and its composites using the transient plane source (TPS) method. Results showed that thermal conductivities of the roll-mill produced VGCNF/silicone ...
Asphalt solar collector (ASC) is a conductive asphalt concrete and an eco-friendly method to de-ice roadways. This study examined if the addition of conductive fillers and various mixing parameters could improve the thermal conductivity and energy efficiency of ASC. A thermal conductivity system measured the thermal conductivity of the concrete samples using the transient plane source (TPS) method. Results showed that thermal conductivity was mostly improved by higher asphalt temperatures, ...
Aerogels have a wide range of properties that make them effective thermal insulators. However, these properties are lost when the materials absorb too much water. The goal of this experiment was to determine how temperature and humidity affect the insulative properties of silica nano-porous aerogels. A thermal constants analyzer measured the thermal conductivity of moist silica nano-porous materials using the transient plane source (TPS) method. Results showed that the thermal ...
Synthetic polymers in starch-based polymer formulations improve the thermal and mechanical properties of the compounds. The purpose of this study was to develop and analyze foams containing ethylene-vinyl acetate (EVA) and varying concentrations of corn starch. A Thermal Constants Analyser measured the thermal conductivity of the EVA/starch samples using the transient plane source (TPS) method. Results showed that the thermal conductivity of the blends increased with starch content. The ...
In this paper, cost efficient RVC foams were fabricated from household cleaning pad waste (CPW) and sucrose. A thermal analyzer measured the thermal conductivity of the RVC foams using the transient plane source (TPS) method. Results showed that the thermal conductivity of the CPW foams were significantly lower than Ultramet’s RVC foams which are highly insulative. This study proved that it is possible to reproduce low-cost carbon foams from ...
