The application of modified mixture rule for description of modulus of elasticity of nanocomposites poly(methyl methacrylate)/carbon nanotubes
It is shown that the simple rule of mixtures describes correctly the elastic modulus of polymer/carbon nanotubes nanocomposites, if the real characteristics of the nanofill are used instead of the nominal ones. These characteristics are determined by the structure of carbon nanotubes in the polymer matrix. The factor of effective length (aspect ratio) of carbon nanotubes pays the main contribution to nanocomposites stiffness.
