Abstract

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.
