Three Dimensional Homogeneity Characterization in Composite Materials

The turn of the evolution in plastics came with the development of fiber reinforcements. With the introduction of reinforcement fibers to a base resin, the mechanical properties are improved drastically, allowing for the product to be implemented in a wide range of applications. These materials were discovered to have half the weight of their metal counterparts and a tensile strength that is more than doubled. Fibers within the system are ...


Optimization of Instrument Cooling Time for Measuring Thermal Properties with the Thermal Constants Analyzer

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....


Measuring the Thermal Conductivity of Thin Samples of Electrically Insulating Materials

This work introduces a specifically designed sensor to measure the thermal conductivity of thin, insulating materials. This sensor, referred to as the hot square sensor, is unlike the standard sensors, in the sense that it is square in nature, and does not have two, thin layers of Kapton insulation on either side of the thin, metal heating spiral. The lack of Kapton allows a good thermal contact between the sample ...


Rapid thermal conductivity measurement with a sensor: Part 1. Theoretical considerations

This article explains the theory behind the Transient Plane Source (TPS) technique. The method measures the thermal conductivity and diffusivity of materials (solids, liquids, gels, etc.), in a rapid, non-invasive and highly accurate manner. The TPS method is a great technique to be used for thermal characterization as it has a wider thermal conductivity range (0.005 – 500 W/mK) and an easy set-up. The sensor serves as both a temperature gauge and ...
