Our recent theoretical and experimental investigations demonstrated the physical possibility of generation and further propagation of bulk strain solitary waves in waveguides made of nonlinearly elastic materials, namely glassy polymers: polystyrene and polymethylmethacrylate. These materials are widely used as matrices for polymeric nanocomposite materials, with an addition of a wide range of fillers that can drastically change the resulting elastic characteristics of a nanocomposite. Mechanical properties of nanocomposites depend, among other parameters, upon the filler content as well as upon an adhesion of its particles to the matrix. Here we present first experimental results on bulk strain soliton generation in a waveguide made of polymeric nanocomposite.
