In Aerogels, nanoparticles are connected together to form loosely connected network, leaving very high fraction of empty space (or porosity). Due to this high porosity, aerogels have exceptional properties such as low density, low dielectric constant and low thermal conductivity. Traditional Silica Aerogels, however, have limited use as thermal insulation material because of its cost. The present study is aimed at investigation of mechanical properties such as Tensile Strength, Stiffness and Compressive Strength of Aluminium Hydroxide / Epoxy composite filled with Silica Aerogel material. The Thermal Conductivity is also evaluated experimentally. As per ASTM standards, the test specimen's preparation and testing is carried out, and results are presented.
