“…The knee angle of the STF-im-AR fabric was lower than that of the AR fabric, and the knee angle in both fabrics decreased with increasing shear strain rate. It is likely that the STF suspension partially filled the space between the fibers or tows, thereby impeding the shear deformation and compaction of the fabric and resulting in a shift of the knee angle due to yarn locking [33,54,55].…”

Shear-thickening fluid-impregnated aramid (STF-im-AR) fabrics have been manufactured for advanced soft body armor applications for which they provide improved ballistic and stab resistances. It is not yet clear whether or not such improvements can be attributed solely to the STF. In this study, the rate-dependent behavior of an STF-im-AR fabric was investigated at the fabric level, using uniaxial tensile, bias-extension, and picture-frame tests. Rate-dependent behavior of the STF-im-AR fabric was observed during uniaxial tensile testing; however, the effect of the STF treatment was slight and consistent with only the inherent effect of the polymeric nature of its constituent fibers. The shear rigidity of the STF-im-AR fabric increased, due to the presence of the STF and the sensitivity of the fabric's shear stiffness to changes in the shear strain rate also increased slightly. This rate-sensitive shear stiffness of STF-im-AR fabrics may contribute to improved ballistic and stab resistances.

“…In previous works, STFimpregnated aramid (STF-im-AR) fabrics were manufactured, demonstrating enhanced stab and ballistic resistance [7,22,26,32]. Experimental research has suggested many cooperative mechanisms to explain the improvement during penetration testing [14,33],…”

“…This gripping mechanism is done by either an external or a self-clamping force that is almost uniform over the entire clamped length of the specimen, with friction acting on both sides of the specimen. Shim et al [5] tested the dynamic tensile properties of Twaron ® fibres using a specially designed direct clamping device. ASTM D3379 (Standard test method for tensile strength and Young's modulus for high-modulus single-filament materials, withdrawn in 1998 with no replacement) [6] introduced an adhesive gripping method which adheres the test fibres onto a mounting tab with a centre hole or a longitudinal slot of a fixed gauge length.…”
