Description
Summary:The effect of nanofiller particles with various shapes and chemical nature on the physical and mechanical characteristics of the cured epoxy oligomer-based composites has been considered. As is established, the highest physical and mechanical characteristics of epoxy nanocomposites are enriched independently on the origin of the initial nanoparticles at the aggregate size of ~140–300 nm. Herewith, the strength increases by ~1.5 times, the elastic modulus is 2.5 times higher, and the shock viscosity (the crack resistance) of nanosystems in the optimum amount redoubles the shock viscosity.
