Investigating Elastic Properties of the Material with the Nanopowder in its Structure

The work is aimed to develop technologies for heterogeneous materials and to study their physical and mechanical characteristics based on epoxy oligomers ED-20 and Praimer-204 filled with silica fume - tarkosil. The experiments show that filler’s size and concentration depends on mechanical properties of heterogeneous material. The maximum rise of Young modulus at 12% volume filler concentration makes up 23%. When ultrasound dispersion is used maximal rise of the elasticity modulus (32%) is fixed at 25% nanopowder content. It was shown that Young modulus depends on the characteristic size of the filler at a constant concentration. Experimental and theoretical Young modules were compared.
Key words: heterogeneous material, nanoparticles, epoxy resin, mechanical properties.
