Abstract
Experimental dynamic tests for energy absorption by four selected auxetic fabrics were conducted and analyzed. An original test stand was designed, manufactured and attached to a Hopkinson's bar. The energy absorbed by an auxetic curtain was expressed in terms of the energy of the maximum elastic deformation of a unit volume along the support line of the witness-plate. A quasi-impulse load was induced using a gas blast under a pressure corresponding to an indoors deflagration explosion of a propane-air mixture in a vented room. The auxetic fabric with the best energy-absorption properties was identified on the basis of the comparative analysis using a reference system with a steel specimen.
