Prediction of on-axes elastic properties of plain weave fabric composites

Prediction of Elastic Properties of Plain Weave Fabric Using Geometrical Modeling

“…The complex mechanic properties of the combination of the warp and weft yarns interlaced in woven fabric can be possible to be constructed as follows. Fig.5a illustrates a unit cell (Naik & Ganesh, 1992) of woven fabric lamina. There is only one quarter of the interlacing regin analysed due to the symmetry of the interlacing regin in plain weave fabric.…”

“…Along the warp direction, i.e., in the Y-Z plane (Fig. 5(a) (Naik & Ganesh, 1992) Along the weft (fill) direction, i.e., in the X-Z plane (Fig. 5(a) …”

“…The slice array model (i.e., SAM) (Naik & Ganesh, 1992), which considers the actual yarn cross-sectional geometry and the presence of a gap between the adjant yarns, is presented for the elastic analysis of 2-D orthogonal plain weave fabric lamina. The shape functions agree well with the actual geometry of the woven fabric lamina.…”

“…Thus, the developed prediction models need quite a lot of tedious preparing works and large computation. In this study, a unit cell model based on slice array model (SAM) (Naik & Ganesh, 1992) for plain weave is developed to predict the elastic behavior of a piece of woven fabric during extension. Because the thickness of a fabric is small, a piece of woven fabric can be regarded as a thin lamina.…”

Mechanical Analysis of Woven Fabrics:The State of the Art

“…The drawback of this approach, reported also by the authors, was the consideration of the tow undulation in one-direction that is a non-realistic assumption for woven fabrics. Naik expanded the above approach taking into account the strand crosssection geometry, possible gap between two adjacent strands and the two-direction undulation geometry (Naik & Ganesh, 1992). Actually his detailed model demands a large www.intechopen.com…”
