Abstract
Understanding of microscopic deformation behaviour of plain weave fabric lamina is essential in the analysis of the macroscopic mechanical properties of woven fabric composites. Many analytical models have been proposed to predict elastic properties of woven fabric laminae. The present paper is an attempt is made to fit experimental data obtained from the analysis of fibre deformation using Raman spectroscopy to the slice array model (SAM) to predict the local fibre strain distribution in the loading direction along the defined cell of a plain-weave lamina. Another model is proposed that combines the slice array and the off-axis (crimp) model and the experimental data are shown to fit this model rather better.
