Thermal characteristics of polymer composites are similar to the properties of metal, with the mechanical properties being similar to plastics. Thermal conductivity of a polymer composite depends on geometry of the filler, and interaction and dispersal of the filler within the polymer matrix. In this study, thermal conductivity of copper and Al₂O₃ filled polymer composites were investigated. A Thermal Constant Analyzer was used to measure thermal conductivity of the ...
The transient plane source (TPS) technique has a wide range of applications because of its capability to test solids, liquids, powders, and anisotropic materials over a range of sizes. Thermal properties of thin films and coatings can also be characterized using the TPS method if the samples are placed between the sensor and a bulk background. To minimize errors with the TPS method, use identical materials on each side of ...
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 ...
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 ...
Traditional alloys are composed of approximately one to two major metal elements, such as aluminum, and titanium, etc. For the purpose of casting molds, new research has led to the creation of high-entropy (HE) alloys, that encompass five or more major metal elements. This research led to the discovery of lower thermal properties in HE alloys, portraying them as potential coatings in the management of casting molds. Low thermally conductive ...
