In order to study the anti-blast performance of flexible fabrics, the dynamic response and failure behavior of aramid fabric under blast impact were analyzed with the numerical simulation method. Mechanical tests of aramid fabric H I 000D-AP220 were carried out, and the constitutive model for woven fabric and the explosive numerical analysis model were established. The dynamic responses and failure modes of the fabrics under different loads were obtained by the analysis of fabrics with different thicknesses and different stacking angles. The results show that, there are 2 typical failure modes of fabrics under the explosive impact: the failure of the central hole and the tensile tear at the boundary, with obvious folds in the width direction of the fabric. The front and back layers absorb more energy than the middle ones. Better anti-explosion ability can be achieved through adjustment of the fabric stacking angle. [ABSTRACT FROM AUTHOR]
