Commercial high-performance fibre materials for body armour have very low surface friction and this has become an issue in the effectiveness of ballistic impact energy absorption. Also, the incidence of sports injuries in high contact sports is high. The severity of injuries of police and sportsman can be reduced by wearing enhanced protective clothing that have the ability to absorb the shocks. In this study, a type of non-Newtonian fluid has been developed. It became hardened upon a shock impact which was observed through a drop-on-weight test. The non-Newtonian fluid was successfully applied on to a traditional plain weave body armour fabric made of Twaron®. The treated fabric was studied by scanning electron microscopy and a yarn pulling-out test. It shows that the force to pull out a yarn from the non-Newtonian fluid treated fabric is four times higher than that of the untreated one. The flexibility of the non-Newtonian polymer treated fabric remains unchanged. The polymer can be used for applications where impact protection can be a highly desirable property.

非牛顿流体浸渍复合织物防护纺织品的研究

用于防弹衣的商用高性能纤维材料具有非常低的表面摩擦，这已成为弹道冲击能量吸收有效性的问题。此外，高接触运动中运动损伤的发生率很高。通过穿着能够吸收冲击的增强型防护服，可以减轻警察和运动员受伤的严重程度。在这项研究中，开发了一种非牛顿流体。通过落锤试验观察到的冲击冲击后，它变硬了。非牛顿流体成功应用于由 Twaron® 制成的传统平纹防弹衣织物。通过扫描电子显微镜和纱线拉拔试验研究处理过的织物。它表明从非牛顿流体处理的织物中拉出纱线的力是未处理织物的四倍。非牛顿聚合物处理过的织物的柔韧性保持不变。该聚合物可用于冲击保护可能是非常理想的特性的应用。
