The main objective of this research project was to create a material with a very low thermal conductivity at high temperatures, for the conservation of energy in high temperature systems. To accomplish this goal, the researchers incorporated carbon nanofibers into the mesoporous network of monolithic aerogels, with up to a 20 wt.% through an accelerated-gelation sol-gel process. The synthesis process also involved the use of supercritical drying of the aerogels to ...
The thermal properties of a series of treated and untreated oil palm fiber-reinforced composites were tested at room temperature and atmospheric pressure using the TPS method. Treatment of the composites with varying methods resulted in increases in thermal conductivity, porosity and pore sizes depending on the treatment method used. The dependence of thermal conductivity on temperature was also studied and it was found that the maximum thermal conductivity was at ...
Through the use of thermal conductivity and moisture related measurements, this article investigates the physical properties of undergarments of different compositions (cotton, polyester, rayon, viscose, etc.). This research is used to determine which types of materials would best be suited for use in sports/day-to-day/comfortable clothes. Important properties measured include the porosity of the material as that affects the ability for moisture to be released, as well as the ...
The effective thermal conductivities of fully expanded intumescent chars are estimated using a finite element model related to porosity and density of the chars....
Through the use of the transient plane source method the researchers were able to measure the thermal conductivity of a collection of cellular metals as well as the in- homogeneities of the samples. The volume of the samples was varied and the density of these individual volumes was calculated from tomography....
