This research aims to determine the effect of altering filler particle sizes and shapes, on the thermal and mechanical properties of polypropylene (PP). Fillers such as thermally reduced graphite oxide (TRGO), multi-layer graphene (MLG250), carbon black (CB), multiwalled nanotubes (MWNT) and expanded graphite (EG), were added to the PP base. A thermal analyzer was used to measure the thermal conductivity of the various PP composites. Results determined that the PP ...
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 ...
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 ...
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 ...
Boron Nitride filled epoxy composites are explored on a thermal and mechanical scale within this research article. Researchers took special interest in the effect of filler content, mixing conditions and Boron Nitride agglomerate size, on the thermal conductivity of the composite. Experimental results alluded to an increase in thermal conductivity, as filler content, and mixing speed, time and temperature increased. On the other hand, as the Boron Nitride agglomerate size ...
