Mesostructure and porosity effects on the thermal conductivity of additively manufactured interpenetrating phase composites

This article explored the relationship between structure and thermal conductivity in additively manufactured interpenetrating A356/316L stainless steel composites. The thermal conductivities were determined using the transient plane source (TPS) method. The thermal conductivity of a 43 vol% 316L composite was found to be 53 W/mK. This was a much lower value than what was predicted by the rule of mixtures approximation. This was believed to happen because residual porosity degrades ...

Damage-tolerant metallic composites via melt infiltration of additively manufactured preforms

This article studied A356/316L composites which were fabricated by infiltrating additively manufactured 316L lattices with molten A356. Various tests were conducted on the properties of the composites to determine if the two-step processing used to manufacture them avoided the issues that current fusion-based additive manufacturing techniques have. The thermal conductivity of the composites was determined with the transient plane source (TPS) technique. The results showed that the thermal conductivity ...

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....

Experimental and numerical investigation on integrated thermal management for lithium-ion battery pack with composite phase change materials

In this study, thermal behaviors of an integrated thermal management system (ITMS) with phase change materials (PCMs) and air conditioning exhaust are examined. To enhance thermal conductivity of the PCM, copper foam and paraffin were added. Thermal conductivity of the composite PCM was measured by a thermal analyzer, based on the transient plane source method....

Fabrication, proposed model and simulation predictions on thermally conductive hybrid cyanate ester composites with boron nitride fillers

In the present study, boron nitride/dicyclopentadiene bisphenol cyanate ester/bisphenol A dicyanate ester (BN/DCPDCE/BADCy) composites were investigated for the effects of filler mass on thermal and mechanical properties. Thermal conductivity was measured using an instrument by transient plane source method. With the addition of BN fillers for BN/DCPDCE/BADCy composites, the BN-BN connections of inner composites increased and formed more thermally conductive channels, resulting in improved ...
