The impact of water-induced degradation on the mechanical properties of the chosen two PTFE-coated, glass threads woven fabrics is investigated in this paper. The paper begins with a survey of literature concerning the investigation and determination of coated woven fabric properties. The authors carried out the uniaxial tensile tests with an application of flat and curved grips to establish the proper values of the ultimate tensile strength and the longitudinal stiffness of groups of specimens treated with different moisture conditions. Despite the water resistance of the main materials used for fabrics manufacturing, the change of the mechanical properties caused by the influence of water immersion has been noticed. The reduction in the tensile strength resulting under waterlogged is observed in the range from 5% to 16% depending on the type of investigated coated woven fabric and direction of weft or warp.

The stratospheric airship envelope material is operated in biaxial stress, so it is necessary to study the in-plane biaxial tensile strength. In this paper, a theoretical model is developed to evaluate the mechanical properties of in-plane biaxial specimens. Being applied to the finite element analysis, the theoretical model is employed to evaluate the influence of strengthening material behavior (E*) and geometry parameters on the mechanical behavior in the central. The follows results are drawn: (i) smaller the length of the central region (Lcen), E* and larger the central region corner radius (r) contribute to smaller coefficient of variation (CV); (ii) smaller Lcen and larger E* contribute to smaller stress concentration factor (k), k in the limit state of r is larger than that in other conditions. (iii) The CV and k under stress ratio of 1:1 are smaller than those under other stress ratios. The study can provide a useful reference for the design of biaxial specimens.

“…A good gas barrier property is needed for some special applications such as coated or laminated envelop for inflatables, transparent and flexible packaging, sport balls, biomimetic materials, pneumatic tires, corrosion resistant coatings, and many others, where polyurethane-based coatings or films are frequently used. [3][4][5][6] Therefore researchers have used many approaches for improving gas barrier property of polyurethane, like modifying structure-morphology [7][8][9][10][11][12] or incorporating nanoplatelets such as nano-clay 11,[13][14][15][16][17] or graphene 18,19 in TPU matrix. TPU/clay nanocomposites exhibit enhanced mechanical as well as gas barrier properties in comparison to neat polyurethane.…”

“…In addition to these, high permeability to different gases is another drawback of polyurethane. A good gas barrier property is needed for some special applications such as coated or laminated envelop for inflatables, transparent and flexible packaging, sport balls, biomimetic materials, pneumatic tires, corrosion resistant coatings, and many others, where polyurethane‐based coatings or films are frequently used . Therefore researchers have used many approaches for improving gas barrier property of polyurethane, like modifying structure‐morphology or incorporating nanoplatelets such as nano‐clay or graphene in TPU matrix.…”

Thermoplastic polyurethane (TPU)/clay nanocomposite films were produced by incorporation of organo‐modified montmorillonite clay (Cloisite 30B) in TPU matrix by two different melt‐mixing routes (direct and master‐batch‐based mixing), followed by compression molding. In master‐batch mixing where the master‐batch was prepared by mixing of clay and TPU in a solvent, better dispersion of clay‐layers was observed in comparison to the nanocomposites produced by direct mixing. As a consequence, superior mechanical and gas barrier properties were obtained by master‐batch mixing route. The master‐batch processing resulted in 284 and 236% increase in tearing strength and tearing energy, respectively, with 5 wt % clay‐loading. Interestingly, in case of master‐batch mixing, the tensile strength, stiffness as well as breaking extension increased simultaneously up to 3 wt % clay‐loading. The helium gas permeability reduced by about 39 and 31% for the TPU/clay nanocomposites produced by mater‐batch and direct mixing routes, respectively, at 3 wt % loading of clay. Finally, the gas permeability results have been compared using three different gas permeability models and a good correlation was observed at lower volume fraction of clay. © 2018 Wiley Periodicals, Inc.
