Why is it important?
Since the mechanical performance of polymer nanocomposites are impressed by their rheological properties which is affected by the filler structure and content, the aim of the present work is to investigate the mechanical, rheological and thermal properties of epoxy nanocomposites reinforced by silica aerogel with mesoporous structure as a filler with a particular emphasis on identifying fundamental structure–property relationships. Moreover, the mechanisms that contribute to the fracture behavior are investigated by studying the fracture surface of the toughened silica aerogel-epoxy nanocomposites.
Perspectives
Adding the silica aerogels led to an increase in storage modulus (11%), Tg (5 °C), Young’s modulus (35%), tensile strength (62%) and toughness (126%).
