AB  - Polymeric nanocomposite materials present potentials in applications with high-rate loading. In the experiments to determine the dynamic response of such nanocomposites, we used pulse shaping techniques on a split Hopkinson pressure bar (SHPB) for constant-strain-rate deformation under dynamically equilibrated stresses in specimens such that accurate stress-strain curves at various dynamic strain rates were obtained. Corresponding quasi-static stress-strain was also obtained to study the rate effects over a wide range. In this paper, the dynamic and quasi-static compression experimental results are presented and discussed on two types of polymeric nanocompositres: a polycarbonate (PC)/clay nano-composite and a set of epoxidized soybean oil (ESO)/clay nanocomposites with various nanoclay weights. Strain-rate and nanoclay weight effects on the compressive properties of the nanocomposites were experimentally determined.
