Abstract

Two-dimensional woven fabric composite models are presented for the elastic analysis of orthogonal plain weave fabric lamina/laminate. Yarn continuity along both warp and fill directions and the actual yarn cross-sectional geometry and fabric geometry are considered in the analysis. Off-axis elastic properties are determined by coordinate transformation. Comparison is made between the off-axis elastic properties of plain weave fabric laminates and cross-ply laminates. It is found that the elastic properties of the plain weave fabric laminates are superior as compared to those of equivalent cross-ply laminates over a large range of off-axis angles.
