In the electronic industry, manufacturers depend on accurate thermal conductivity testing methods to characterize their new products, and perform quality control maintenance on continuing materials. This paper assesses the ability of the Transient Plane Source (TPS) technique to accurately characterize newly developed materials, for their use in novel electronic applications. Using the TPS technique, various silicone based electronic materials, of differing filler contents, were thermally characterized and examined for their ...
This study aimed to determine the effect of instrument temperature cooling time on the accuracy of thermal conductivity measurements. Multiple samples, with varying thermal conductivities, were measured using the Thermal Constants Analyzer, and with five different cooling times. Cooling times, and their effect on the thermal conductivity results were analyzed, and appropriate cooling times were suggested, based on the findings....
Presently, society has become infatuated with limiting their carbon-foot print. As this progresses, scientists must find alternative means for manufactured composites: natural composites. One way this has been put forth is the addition of betel nut husk (BNH) as a reinforcing material in vinyl ester (VE) matrices (polymer composites). Thermophysical tests were conducted, using a TPS sensor, to determine the thermal properties of the composites. Mechanical and thermal degradation tests ...
This work introduces a direct method for measuring the specific heat of solids, using the Transient Plane Source Technique (TPS). To begin, a sample is placed into a thermally conductive holder, surrounded by a thermally insulating material. A thermally conductive sample holder is used, to limit the time it takes to achieve a temperature equilibrium between the holder and the sensor. Insulating the sample holder is to minimize heat loss ...
Using a solid hot stretching technique, highly-oriented polyoxymethyelen (POM)/multi-walled carbon nanotubes (MWCNTs) composites were created. Thermal properties were analyzed both in the stretched and through-plane directions. Researchers found that by increasing the draw ratio, to as high as 900%, the thermal conductivity of the composite has improved in the stretching direction, when compared to the material prior to this process. Researchers also determined that the thermal conductivity of the MWCNTs ...
