The analysis of a pultruded E-glass reinforced polyester (GFRP) composite is performed by TGA, DSC and DMA methods. The data obtained from these analysis methods agreed well with theoretical models applied to the GFRP. The specific heat capacity of the composite was found to decrease over heating and the decomposition process....
The thermal and mechanical properties of 4 different types of concrete were studied in the temperature range of 20°C to 800°C. Thermal properties studied include: thermal conductivity, specific heat and thermal expansion. Data generated from the testing of these samples using the TPS method were used in order to generate simplified expressions of thermal and mechanical properties as a function of time....
Through the use of experimental (one-sided TPS technique) and theoretical (MD simulations) methods, the thermal conductivity and thermal diffusivity of methane hydrate was studied. Varying concentrations of methane hydrate were studied. The effect of pressure on the thermal properties of methane hydrate was also studied and didn't have a significant effect on the measurement of thermal conductivity. The results obtained from the experimental and theoretical methods agreed well with each ...
Through the use of thermal conductivity and moisture related measurements, this article investigates the physical properties of undergarments of different compositions (cotton, polyester, rayon, viscose, etc.). This research is used to determine which types of materials would best be suited for use in sports/day-to-day/comfortable clothes. Important properties measured include the porosity of the material as that affects the ability for moisture to be released, as well as the ...
The authors look into problems with accurately measuring thermal conductivity of liquid samples. Among these problems is the onset of natural convection during the measurement of thermal properties, which may lead to skewed values reported after characterization. The effect of natural convection is analyzed numerically for the transient plane source method in order to determine at what time during an analysis the convection causes incorrect output data. The effect of ...
