Features of the experimental determination of the elastic characteristics of epoxy resin with the addition of silicon dioxide nanoparticles

Abstract

Current work describes experimental determination Young modulus of polymer composition based on epoxy resin filled two types of silicon dioxide nanoparticles with different average diameter. It is shown, that each type of powder differently increases the Young's modulus of the epoxy resin for constant concentration. For Tarkosil powders, the increase in Young's modulus for filled epoxy was from 7 to 25% with a decrease in the average particle diameter from 48 to 18 nm. The change in the Young's modulus of the polymer is significantly less with the addition of Aerosil powders. Young's modulus increased from 0 to 15% with diameters from 12 to 8 nm.
