摘要: 为了研究Vectran纱线是否符合飞艇蒙皮材料的性能要求,探究捻度对Vectran长丝纱的力学性能的影响,并织造Vectran平纹织物。通过比较四种不同的Vectran织物的拉伸、撕裂性能,讨论涂层对Vectran织物力学性能的影响以及不同的撕裂失效模式。结果表明:加捻可以增强Vectran长丝纱的断裂强力,但需要特殊工艺,随着捻度增加,强力出现先降低后增加再降低的趋势;成本更低的400D Vectran织物可以达到飞艇蒙皮材料的力学性能要求;Vectran涂层织物与未涂层织物的撕裂失效模式不同。

Abstract: In order to study whether a Vectran fiber can be made into a fabric that meets the performance requirements of airship envelope material, the mechanical properties of the yarn and fabric were tested respectively. Firstly, the effect of twist on mechanical properties of Vectran filament yarn was investigated by breaking strength test and data fitting. The results show that twisting can enhance the breaking strength of Vectran filament yarn, but special twisting technology is needed. As the twist increases, the strength decreases first, then increases and then decreases. Additionally, by comparing the tensile and tearing properties of four different Vectran fabrics, the influence of coating on the mechanical properties of Vectran fabrics was discussed. The results show that the 400D Vectran fabric can meet the mechanical properties of the airship envelope material and has the advantage of lower cost. The tear failure mode of Vectran coated fabrics is different from that of uncoated fabrics.
