abstract Preliminary comparative static identification experimental tests on four selected commercial auxetic woven fabrics were conducted in terms of the tensile test in the auxetic fibre direction. A new method of such tests was developed, based on capstan grips as well as on video-extensometer and extensometer techniques. The identification tests were carried out at temperatures of 20 and 180°C due to the intended use of auxetic fabric as a protective curtain against a shock wave induced by a gas explosion. The ultimate tension force per unit width of fabric, effective Poisson’s ratios in the fabric plane and in the transverse plane, as well as the absorbed energy were determined approximately. The auxetic fabric with the relatively best properties was selected.
