Abstract

In this research, nano pore composite had an effect on enhancing thermal property and mechanical property. The nano pore composite maintained the pore structure and enhanced mechanical property. Al2O3 xerogel was collapsed after heat treatment over 1000&2103; and they had weak mechanical strength because of pores. For maintenance of pore at high temperature and improvement of mechanical strength, Al2O3 whisker was hybridized. The Al2O3 whiskers in nano pore composite play the role of pillar during heat treatment. The mechanical property of Al2O3 xerogel was improved through complexation with Al2O3 whisker. The elastic modulus of nano pore composite increased 225 % from Al2O3 xerogel.
