Effect of Nanoparticle Modification on Static and Dynamic Behaviour of Foam Based Blast Energy Absorbers

Original language description

The effect of multi-wall carbon nanotubes and nanosilica (nano SiO2) content on physico-mechanical properties of glass microspheres-epoxy resin composite, designed for blast energy absorbing applications, was evaluated experimentally. Specific porous lightweight foam with high volume fraction of microspheres (70 vol.%) was prepared and modified by 1 to 5 vol.% of multi-wall carbon nanotubes and nanosilica. Compressive and flexural strength tests were conducted at quasi-static load. Split Hopkinson Pressure Bar apparatus was used to obtain high velocity characteristics of the materials. The relative absorbed energy was calculated to assess the relation between the composition of the material and its shock wave attenuation capacity. The mixtures containing nanosilica exhibited an increasing trend in the energy absorption capacity with increasing nanoparticle content up to 4 vol.%. The addition of carbon nanotubes also increased absorbed energy (again up to 4 vol.%, a significant drop was observed at higher concentrations). Comparing the values of the relative absorbed energy, the carbon nanotubes composites prevail over the nanosilica modified ones.
