This study presents the fabrication of lightweight, strong, high-helium barrier, and weather-resistant composite laminates for stratospheric airships. Three high-performance fabrics (Spectra®, Vectran®, Kevlar®) served as the strength layer, while PVDC-treated BOPET film (Mylar®) and PVF film (Tedlar®) acted as the helium barrier and the weather-pr...
Lighter-than-air (LTA) vehicles like aerostats and airships are increasingly favored for high-altitude surveillance and communication missions. These vehicles employ a fabric enclosure filled with helium for lift, enabling efficient payload transport to predetermined heights. Impermeable coated or laminated inflatable textile structures have been e...
In terms of communications and scientific observations, a stratospheric airship can be an effective alternative to the artificial satellites in Earth’s orbit. For an airship to float in the low air-density stratosphere, it must be designed with light, flexible, and strong materials. In the present study, we have designed and developed six different...
The authors have retracted this Conference Paper as they do not have permission to publish the data reported. All authors agree with this retraction.
The aim of the present study was to develop a continuous laminated material system that could be very lightweight, having very high strength, extremely low helium permeability. In this paper, a multilayered laminated structure has been designed, prepared, characterized, and developed using high-performance fabric including para-aramid fabric as a s...
Aerostats and airships are lighter-than-air (LTA) systems that consist of an envelope filled with a gas having less density than that of ambient air (e.g., hydrogen or helium). Such a system can act as a cost-effective, long-endurance aerial platform for several scientific and military applications, e.g., telecommunications, surveillance, detecting...
In the present work PVA-g-PAN/ZnO nanocomposite films were prepared by free radical graft copolymerization of acrylonitrile on to PVA and subsequent in situ precipitation of ZnO nanoparticles into the polymer matrix. The films were characterized by FTIR, Raman spectroscopy, differential scanning calorimetry (DSC) and Scanning electron microscopy (S...
Abstract: The aim of the present study was to investigate the UV absorption properties of PVA-g-PAN/ZnO nanocomposite films prepared by free radical graft copolymerization of acrylonitrile on to PVA and subsequent in situ precipitation of ZnO nanoparticles into the polymer matrix. The nanocomposites were characterized by various analytical methods...
In the present study ZnO nanoparticles containing poly (vinyl alcohol-g-acrylonitrile)(PVA-g-PAN) nanocomposites membranes were fabricated and characterized by various analytical methods. PVA was grafted with polyacrylonitrile chains by free radical polymerization method and thereafter zinc oxide (ZnO) nanoparticles were impregnated within the poly...
