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 literature concerning the subject of architectural fabrics investigations is very extensive. Performed investigations of the coated woven fabrics have shown that the mechanical parameters are highly influenced by temperature changes [13][14][15]; changes in behaviour under uniaxial, biaxial and creep loadings [16][17][18][19][20][21]; glass threads based and PTFE-coated woven fabrics occur a reduction in the tensile strength resulting under waterlogged [22,23]; prove degradation of the tensile strength exposed to weathering and ageing impacts and cyclic loading [24][25][26][27]; exhibits highly material nonlinearity with identified viscoelastic, viscoplastic behaviour [28][29][30][31][32][33][34]; puncture resistance strength increases with the increase of weight percentage of fibres and initial notch significantly reduce the ultimate strength [35][36][37][38]; the failure strength depends on the stress ratio and off-axial angle [39][40][41][42]. The investigations are also performed on: tearing behaviours and tearing strength propagation mechanisms [41,[43][44][45][46], off-axis tearing properties [47,48], achieving 3D strain surfaces on coated woven fabrics, and refined biaxial test procedures [49,50], modelling multi-scale progressive dam...…”

This research aims to determine the influence of water-soaking on polyester-based coated woven fabrics for ultimate tensile strength and elongation at break under uniaxial tensile tests. The paper begins with a short survey of literature concerning the investigation of the determination of coated woven fabric properties. The authors carried out the uniaxial tensile tests with an application of a flat grip to establish the values of the ultimate tensile strength of groups of specimens treated with different moisture conditions. SEM fractography is performed to determine the cross-section structures of coated woven fabrics. The change in the mechanical properties caused by the influence of water immersion has not been noticed in the performed investigations.

“…However, the uniaxial mechanical tests are limited in characterizing the real mechanical responses of composites under the complex loading state in engineering applications, for example, the filament wound pressure vessels (FWPV) [ 13 , 14 , 15 , 16 ]. Therefore, the biaxial test is significant for identifying the strength of composites under actual working conditions [ 17 , 18 , 19 , 20 , 21 , 22 , 23 ].…”

The biaxial loading properties of carbon-fiber-reinforced polymer (CFRP) are critical for evaluating the performance of composite structures under the complex stress state. There are currently no standardized specimens for the CFRP biaxial experiments. This work developed a new design criterion for the cruciform specimen coupled with the Hashin criterion. The finite element analysis was conducted to investigate the effect of geometric parameters on the stress distribution in the test area. The embedded continuous laying method (ECLM) was proposed to achieve the thinning of the center of the test region without introducing defects. The manufacturing quality of the cruciform specimens was verified by the ultrasonic C-scanning test. The biaxial test platform consisting of the biaxial loading system, digital image correlation (DIC) system, strain electrical measurement system, and acoustic emission detection system was constructed. The biaxial tensile tests under different biaxial loading ratios were conducted. The results showed that the biaxial failure efficiently occurred in the test area of the cruciform specimens designed and manufactured in this paper. The failure modes and morphology were characterized using macro/microscopic experimental techniques. The biaxial failure envelope was obtained. The results can be used to guide the design of composite structures under biaxial stress.
