Preparation and characterization of epoxy resins filled with submicron spherical zirconia particles

摘要

Submicron spherical zirconia particles were synthesized and used as a reinforcement for epoxy resins.In fact,recent developments indicate that a significant improvement in the thermoset polymer performance may be obtained by using submicron inorganic filler.In this paper,different composites with weight fraction of the filler in the range 1-5 % were prepared and characterized in terms of mechanical properties.A numerical model suitable for the description of such materials was set up and employed to estimate the properties as functions of the reinforcement content.
