Sebacic acid (SA) can be absorbed into the pores of expanded graphite (EG) to form a SA/EG composite phase change material (PCM). There is no chemical interaction between the SA and EG, they are merely integrated. The optimal amount of SA was found to be 85 wt.% of the total mixture. The 85 wt.% composite had a phase change temperature of ~ 128°C, with a latent heat of ~ 187 J/g. The thermal ...
Epoxy resin/silicon carbide (Ep/SiC) composites were prepared by the casting method and subsequently characterized for their mechanical and thermal properties. It was determined that an increasing mass fraction of SiC in the epoxy resin resulted in increasing thermal conductivity of the composites. Using 50 wt.% SiC resulted in a thermal conductivity of 0.7152 W/mK, which is three times that of pure epoxy resin. Mechanical properties peaked with 10 wt.% SiC. ...
Using industrial grade mullite powder and a foaming and starch consolidation process, a series of porous mullite ceramics were prepared. These ceramics were analyzed by a thermal constants analyzer, and it was determined that the ceramics had low thermal conductivities and would make good thermal insulators. The porosity of the synthesized ceramics can be controlled by the sintering temperature and by adjusting solid loading. The ceramics were subjected to theoretical ...
The pyrolysis of rice husk was performed in order to product bio-oil which was then analyzed for its elemental and chemical composition, basic fuel properties, distillation, thermal properties, etc. Also, the effect of addition of methanol to the bio-oil was studied and it was concluded that the addition of methanol to the bio-oil was beneficial. Thermal analysis was performed by a Thermal Constants Analyzer and via thermogravimetric analysis (TGA)....
Microencapsulated phase change materials (MPCMs) are excellent materials for the storage of thermal energy, and through their dispersal into a carrier fluid, microencapsulated phase change slurries (MPCS) can be prepared. These slurries exhibit both excellent thermal energy storage and heat transfer properties. A series of MPCS were prepared for this research and subsequently tested for thermal conductivity and specific heat. Other methods of quantification include DSC, TGA, rheometry, and infrared ...
