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 analysis of a pultruded E-glass reinforced polyester (GFRP) composite is performed by TGA, DSC and DMA methods. The data obtained from these analysis methods agreed well with theoretical models applied to the GFRP. The specific heat capacity of the composite was found to decrease over heating and the decomposition process....
A series of melamine-formaldehyde microcapsules were synthesized using an in-situ polymerization and subsequently characterized for their thermal and structural properties. SEM and FT-IR were used to investigate the structural properties and DSC and TGA were used to investigate the thermal properties. The authors concluded that the thermo-physical properties of the microcapsules were related to the synthesis conditions and the core content of the capsules....
As technology advances, the need for inexpensive polymer-based composites possessing high thermal conductive properties has become more and more important. Previously, the addition of thermal conductive particles, such as alumina, boron nitride and alumina nitride, has caused an increase in the thermal conductivity of the composite. Although an increase in thermal conductivity is present, an increase in fabrication costs is also experienced as a higher quantity of particles is required, ...
Thermal conductivity measurements of the same samples were carried out using the TPS method. Thermal testing on carbon nanotubes to study for promising fillers. Thermal conductivity of single-walled carbon nanotubes should enable a further reduction in the filler content required for a given enhancement in the composite properties. For the multi-walled carbon nanotube thermal conductivity increased modestly using this method whereas for the single-walled carbon nanotubes the thermal conductivity was ...
