Deformation of Aramid Fabrics with Different Structures During Low-Speed Penetration by an Indenter. Review

Resumo

We have studied the characteristic features of deformation in aramid fabrics with different weaves during penetration by an indenter (in the form of a double-edged knife) at slow speed. We have established a relationship between the degree of binding of warp and weft yarns in the fabric and its resistance to stabbing with a knife. In order to achieve significant frictional interaction between yarns during penetration of the knife, yarns in one of the sets of yarns should be crimped as much as possible. The results obtained can be used in developing effective protection from a cold steel weapon.
