Effect of Immersion Mediums on the Structural and Thermal Properties of [EP/Zr02-Y203] Nanocomposites

This research studies is the effects of the chemical solutions on the structural properties and thermal conductivity of the nanocomposite materials. Samples were prepared via the hand lay-up molding method, using epoxy resin as a matrix and a variety of weight ratios of the nanoceramic powder (Zirconia- Yttria) as a reinforcement material with different weight ratios,using hand lay-up molding method. Distilled water H20 and diluted HCl and Na0H solutions were used as immersion mediums. Surface roughness, granularity cumulating distribution and thermal conductivity were investigated. The results showed an increase in the surface roughness and changes in the granularity cumulating distribution and thermal conductivity that were dependent on the type of immersion medium used, as well as on the addition ratio of Zirconia-Yttria.
