本文通过对各种聚合物纤维和纱线的精心内部制造和表征,对螺旋拉伸纱线(Hay)进行了系统的研究。它可以更好地了解干草的伸展行为,以便为特定的应用定制它们的特性。研究集中在三个参数上:组件模数、芯径比和初始包角。结果表明,组分模数差越大、芯径比越大、初始包角越小,最大负泊松比越大,干草的拉伸性能越好。当这三个参数组合在一起时,可以谨慎地使用所有这三个参数,以达到干草所需的伸展性能。此外,瞬时真泊松比分析准确地反映了高应变相关干草的瞬时行为。
This paper presents a systematic study of the helical auxetic yarn (HAY) via careful in-house fabrication and characterisation of a wide range of polymeric fibres and yarns. It provides a better understanding of the auxetic behaviour of the HAY in order to tailor their properties for specific applications. The study focused on three parameters: component moduli, the core/wrap diameter ratio and the initial wrap angle. The results show that a larger difference in component moduli, a higher core/wrap diameter ratio and a lower initial wrap angle can produce a larger maximum negative Poisson’s ratio value and thereby a better auxetic performance for HAYs. All three parameters could be carefully utilised when in combination to achieve the required auxetic behaviour of HAYs. Moreover, the instantaneous true Poisson’s ratio analysis accurately presents the instantaneous behaviour of highly strain dependent HAYs.
