“…Use of equation 8provides a useful check on the validity of the experimental data and although the two methods produced different values for ν weft and for ν warp , they were considered to be within the margin of experimental error. Furthermore, literature values for ν lying in the range of 0.2 to 0.5 for similar materials to those contained within the composite bracket the measured values obtained in this study (Hursa et al, 2009;Kraft, et al, 2014).…”

“…Where Ɛ ସହ is the normal strain at 45° to the x-axis, Ɛ ௫ is the normal strain in the x-axis and Ɛ ௬ is the normal strain in the Y-axis, as defined in Figure (5). Furthermore, in tensile loading, the elastic moduli (E) and Poisson's ratio (ν) of the warp and weft fibre directions can be related to each other (Barbero, 2010;Kraft et al, 2014) according to…”

“…Pan et al [25] studied on the DIC for deformation measurement, and several basic questions were solved. Kraft et al [26] studied the orthotropic elastic constants of a micronic woven wire mesh via DIC; the DIC was used to measure the strain of the material. Pinto et al [27] used the DIC to get the strain field and an analysis of the strain was studied in this paper.…”

In practice, the coated fabric is available in many shapes and sizes, not just rectangle and plane. In order to increase the shape-shifting abilities of coated fabrics, polyurethanecoated multi-axial warp-knitted fabric (PU-CMWKF) is developed. In this paper, the tensile characteristics of PU-CMWKF were investigated. Five groups of tensile experiments, with off-axial angles of 0 , 22 , 45 , 67.5 , and 90 , were conducted under constant velocity. The failure mechanism was explored by analyzing the damaged specimens. Additionally, the deformation behavior of PU-CMWKF in three regions was investigated by utilizing the digital image correlation (DIC) system, and an orthogonal anisotropic model was used to predict the modulus and Poisson's ratio of 22.5 and 67.5 . Research results showed that the apparent modulus of PU-CMWKF strongly depended on the cut of directions. And the failure mechanism under in-plane direction loading suggests that tensile and shear failure act together. The analytical model is validated along five directions in the representation of elastic constant under corresponding small strain.

“…A survey of the literature shows that there are mainly two kinds of methods, namely the theoretical model 4,8,[12][13][14][15][16] and experimental methods, 7,8,[17][18][19][20][21][22] to estimate Poisson's ratios of fabric composites (most of them are woven fabrics). Using the theoretical model method, researchers 4,8,[12][13][14][15][16] have developed analytical models based on the previous classical models, such as the Peirce model, 12 or finite element models of fabric microstructures to reveal the Poisson effect, 4,13 calculate the apparent or real Poisson's ratios, 4,8,13,14 and analyze the influences of yarn properties or fabric structural parameters on Poisson's ratios.…”

“…Therefore, the experimental determination is a more reliable and effective method, 8,[17][18][19] which has been utilized in many recent investigations. 7,11,[20][21][22] Although the experimental method for determining the Poisson's ratios has been used by various authors, there still arise questions about the orientation-dependent characteristics of the Poisson's ratios and about the exact Poisson's ratios for specific stress (or strain) states and bias angles.…”

It is undeniable that full-strain range characteristics of Poisson’s ratios on the behaviors of a fabric composite are crucial. However, there have been relatively few papers devoted to this subject. In this study, tensile tests of seven bias angles with a 15° increment are conducted on a typical coated biaxial warp-knitted fabric (BWKF) to estimate the Poisson’s ratios in full-strain range. By utilizing the digital image correlation technique, experimental results are processed, and detailed responses of strain contours and Poisson’s ratios are determined for specific strain states. Then, two typical types, that is recession and peak types, of the Poisson’s ratio strain curves are proposed and their characteristics evolving with the strain, bias angle and stress state are discussed. Results show that characteristics of Poisson’s ratios and strain contours vary noticeably with the yarn orientations, strain and stress levels. As the strain increases, the Poisson’s ratio of peak type first ascends markedly, and then descends moderately after arriving at a peak, generating three distinct stages: the ascending, peak and post-peak stages; in contrast, the recession type only experiences a downward trend, resulting in two characteristic stages: the recession and stable stages. In addition, there is an M-shaped relationship between the Poisson’s ratio and bias angle, with a local valley at 45°, which is not consistent with results in previous works. This investigation could provide new insights into the orientation dependence, Poisson effect and warp–weft interaction mechanism of BWKFs.
