摘要

目的设计一种复合材料，通过五个浓度梯度的聚氨酯浸渍处理，提高复合材料的静态抗穿刺性能。设计/方法/途径分别详细探讨了聚氨酯浓度、聚酯非织造布数量、组分纤维类型(长丝或短纤维)与静态抗穿刺性能的关系。研究结果为设计具有较好抗静刺性能、制备工艺可行、成本低廉的柔性复合材料提供了新的思路。研究结果表明，聚氨酯浸渍非织造布的抗静电穿刺性能明显提高。同时，随着层数的增加，非织造布的穿刺强度- t先增大后减小，在20层时达到最大值。此外，具有长丝的复合材料具有更好的机械抗力。

The quasi-static puncture resistance of flexible impregnated nonwovens made by filament or staple polyethylene terephthalate (PET) fibers

PurposeThis paper aims to design a composite, aiming to improve the static puncture resistance through polyurethane impregnated treatment with five concentration gradients.Design/methodology/approachThe relationship between polyurethane concentration, the number of polyester nonwovens, component fiber type (filament or staple) and the static puncture resistance is explored respectively and elaborately.FindingsThis study provides a new perspective to design flexible composites with better static puncture resistance, feasible preparation process as well as low cost.Originality/valueThe results show that the static puncture resistance of nonwovens impregnated by polyurethane is improved obviously. Meanwhile the puncture strength-T of nonwovens increases first and then decreases with the increase of the number of layers, and the maximum puncture strength-T is found at 20 layers. Moreover, the composite with filaments illustrates better mechanical resistance.
