The thermal conductivity of thin, high-conducting ceramic bars—commonly used in mechanical tensile testing—is measured using a variant of the short transient hot-strip technique. As with similar contact transient methods, the influence from the thermal contact resistance between the sensor and the sample is accurately recorded and filtered out from the analysis—a specific advantage that enables sensitive measurements of the bulk properties of the sample material. The present ...
Thermal interface resistance results from small gaps and surface geometry mismatches between two materials that make up a composite. Thermal interface resistance is present in most any material that is comprised of two or more components. In the field of thermal interface materials, the majority of novel materials are composites, and thus are subject to thermal interface resistance and thermal boundary resistance (thermal discontinuity at a perfectly bonded interface of ...
The thermal properties of coated paper are investigated and how those properties affect the other properties of the coated paper. Using the TPS system the authors are able to measure the thermal conductivity of coated paper samples. It was found that increasing coating mass led to a higher thermal conductivity which in turn led to a decrease in toner gloss and density....
The transient plane source sensors were used to measure thermal conductivity and other thermophysical properties of infrared transparent materials, while under infrared imaging. The infrared imaging provided evidence of temperature uniformity and symmetry, as well as temperature monitoring of the sensor and material being tested. The upgraded version of the original TPS system was used including a bridge circuit, a digital voltmeter, and a data analysis module...
