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 ...

Effect of nanosized carbon black on the morphology, transport, and mechanical properties of rubbery epoxy and silicone composites

Rubber carbon black (CB)/rubbery epoxy (RE) and CB/silicone composites with different types, loadings, and silane functionalization of carbon black were prepared. These composites were investigated for their electrical conductivities, and their mechanical properties. The thermal conductivity of each composite was also determined using a thermal constants analyzer. It was determined that the incorporation of carbon black into the composites increased the thermal conductivity in all of the samples. ...

Preparation of low-density polyethylene/low-temperature expandable graphite composites with high thermal conductivity by an in situ expansion melt blending process

Low-temperature expandable graphite (LTEG) was blended into low-density polyethylene (LDPE) to prepare composite materials with an enhanced thermal conductivity in comparison to pure LDPE. The thermal conductivity of a composite containing 60 wt. % LTEG was found to be increased by a factor of 23 in comparison to the pure polymer. The LTEG was also found to decrease the melting temperature and degree of crystallinity of the LDPE, and the composites were also ...

Innovant agromaterials formulated with flax shaves and proteinic binder: Process and characterization

Agro-composite materials were produced from flax shaves and the properties of these composites were determined experimentally. The structure and morphology of the composites was determined by scanning electron microscopy (SEM), and their thermal conductivities were determined using the transient plane source method. These properties, as well as mechanical, hydric, and acoustic properties were determined as a function of the structure and size of the flax shaves....

Silver incorporated microencapsulation of n-hexadecane andn-octadecane appropriate for dynamic thermal management in textiles

In this paper, the authors discuss the preparation of microencapsulated phase change materials (PCMs). The PCMs used in this study were n-hexadecane and n-octadecane, and the shell was made up of poly(urea-formaldehyde). The effect of dispersing silver nanoparticles in the shells on the thermal storage properties of these encapsulated PCMs was also investigated. The enthalpies of fusion of the samples were determined experimentally, as was the thermal conductivity. It ...
