Using the transient plane source (TPS) technique, the effect of addition of pine tree particles to styrene butadiene rubber is studied. Thermal conductivity, thermal diffusivity, specific heat capacity and density were all investigated. Varying amounts of the pine tree filler particles were added to the polymer matrix in order to form composites. Increasing amounts of the pine tree filler resulted in higher thermal conductivity and thermal diffusivity, with decreasing specific ...
The author reports on improvements to the transient plane source (TPS) technique which deal with increasing the maximum reliability of the measurements. Optimal time of measurement, sensor temperature measurement, and uncertainty of results are explored. The theory was confirmed by experimental measurements made on polymethyl methacrylate (PMMA)....
The authors investigated the thermal conductivity and thermal diffusivity of two composite materials, marble and magnesium oxychloride cement. The transient plane source (TPS) technique was the method used to determine the thermal properties of the aforementioned composites. The thermal properties were studied in the temperature range from 30 to 150°C....
Using the transient plane source (TPS) technique, the thermal conductivity and thermal diffusivity of concrete and wood samples were measured at elevated temperatures. The measured values are compared to established literature values and show good agreement....
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....
