Experimental study of dynamic properties of porous materials under shock-wave loading

The paper presents new experimental data on properties of porous media under shock-wave loading. We considered materials with different nature of porosity. The porosity in the silicone rubber and the epoxy resin was produced by glass microspheres filler. Open porosity was realized in a fibrous material made from glass fibers with corundum. It was shown that two-wave configuration was formed in materials with closed porosity. Such structure of the pulse with a precursor was not observed in samples with open porosity. As a result of analysis of experimental data, Hugoniots for the investigated materials were obtained.
