Investigation of thermal and mechanical properties of Cu-Al alloys with silver addition prepared by powder metallurgy

This article investigated the effects of silver addition to copper-aluminum (Cu-Al) alloys. These effects were studied by observing the microstructural, thermal, and mechanical properties of the alloy through a variety of methods. A Thermal Constant Analyzer was used to determine the thermal properties (specifically the thermal conductivities) of the alloys by implementing the transient plane source (TPS) method. From this method, it was found that the thermal conductivity and diffusivity ...

Novel Al2O3-SiO2 composite aerogels with high specific surface area at elevated temperatures with different alumina/silica molar ratios prepared by a non-alkoxide sol-gel method

This study investigated new sol-gel methods in the fabrication of Al₂O₃ - SiO₂ composite aerogels. Compared to conventional methods, the Al₂O₃ - SiO₂ composite aerogels were prepared and mixed together. Thermal conductivity of the composite aerogels was measured by an instrument, using a transient plane heat source method....

Thermal conductivity enhancement with different fillers for epoxy resin adhesives

As technology advances, improving the efficiency of heat dissipation by thermal adhesives in electronic devices is becoming increasingly important. In this study, a thermal constants analyzer measured the thermal conductivities of eight different epoxy resin thermal adhesives using the transient plane source (TPS) method. Results showed that the layer-structure fillers enhanced the thermal conductivity of the epoxy matrix the most, while the sharp corner-shaped fillers had the lowest impact on ...

Electrical and thermal conductivities of novel metal mesh hybrid polymer composite bipolar plates for proton exchange membrane fuel cells

A novel technique was used in this research article, to introduce a hybrid mesh to a polymer composite within bipolar plates, for proton exchange membrane fuel cells (PEMFCs). The mesh added was copper or aluminum based, to allow for an increased thermal conductivity of the PEMFCs. Experimental testing confirms this theory, as the copper-meshed hybrid polymer composite showed a thermal conductivity of 30.0 W/mK, while the aluminum-meshed hybrid polymer composite ...

Evaluation for micro scale structures fabricated using epoxy-aluminum particle composite and its application

This research studied the addition of aluminum particles to an epoxy material, for use in micro-scale structures. For our interests, the thermal conductivity of the aluminum-epoxy composite was compared to that of the epoxy alone. Particle size was also taken into consideration during testing. It was determined that the epoxy-aluminum composite has a higher thermal conductivity, than the epoxy alone. Also noted, the larger the particle size, the more thermally ...
