The thermal conductivity and diffusivity of a series of three-phase styrene butadiene composites were investigated using the transient plane source (TPS) technique. Both of the series contained a variable amount of natural rubber, as well as variable amounts of silica and clay. The thermal properties decreased sharply at 10 phr filling, but increased subsequently after that. It was determined that silica resulted in better (higher) thermal properties as compared to clay....
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 ...
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 dynamic plane source (DPS) technique, the thermal properties of highly and lowly thermally conducting materials were measured. The theory behind the technique is explained, and three well known materials are analyzed and the accuracy of the method is found to be within 5% of the actual value....
