Oil-palm fiber reinforced phenolformaldehyde composites were prepared and then tested for their thermal properties. Thermal conductivity and diffusivity were measured using the transient plane source (TPS) technique. The composites were then treated using different methods (alkali, silane and acetic acid treatments) and the thermal conductivity and diffusivity were measured again to see how the treatment affected the thermal properties of the composite. It was found that thermal conductivity increased varying ...
The researchers used the transient plane source (TPS) technique for the measurement of a variety of solid and liquid reference materials in order to assess the capability of the TPS technique. Specifically probe size and contact were studied to see how they affected the transient measurements. In addition, the influence of natural convection on liquid samples was studied. While multiple thermal properties can be measured using the TPS technique, thermal ...
Varying weight percentages of pineapple leaf fiber were added to phenolformaldehyde (PF) in order to generate a composite material. Using the transient plane source (TPS) technique, the thermal conductivities of the varying weight percentage composites were studied. It was found that increasing weight % pineapple leaf fiber resulted in decreasing thermal conductivity and diffusivity of the composites. The experimental results are compared to results produced by two models (the Rayleigh-Maxwell and ...
Using the transient plane source (TPS) method, the thermal conductivities of a series of magnesium integral foams have been measured experimentally. The main factor contributing to the thermal conductivity of the magnesium foams is the bulk density. In addition to using the TPS technique, micro-computed tomography (µCT) was used to explain any deviations from expected thermal conductivity....
