Abstract:

The present approach shows the use of nano-silica / nano-alumina in polyurethane (PU) matrix, which lead tosignificant improvements in the mechanical and thermal properties of the nano-composite. It is observed that withincorporation of 1% of nano-alumina into the PU matrix, there is an improvement in the tensile strength of around50%, and for nano-silica the improvement is around 41%, at the same concentration. The morphological data showsthat above 3% of the nano particles there are agglomerations in the nanocomposite. Again with the absorption ofmoisture, there is a decrease in the thermal and mechanical properties of the PU resin, but in this research workit is observed that with the incorporation of the nano particles, in the presence of absorbed moisture there is animprovement in mechanical and thermal properties of the composite, over that of the PU matrix.
