  Abstract

In this paper, the mechanical properties of a single-ply woven composites are investigated through a combination of multiscale numerical simulation and experimental test. The tensile experiments of three woven structures with different thread counts, 4.5+4.0, 5.5+7.0 and 5.5+5.0, are conducted. A multiscale numerical method is proposed in order to understand the influence mechanism of thread count on the mechanical properties. The numerical predictions have a good agreement with the experimental results. Many unique characteristics of the single-ply woven composites have been observed, such as the clearly nonlinear mechanical behavior of samples with large thread count, the positive transversal normal strain during the initial phase of longitudinal uniaxial tension and the breakage morphology in relation to thread count. The M/L ratio is proposed in this paper to investigate the effect of the difference in the thread count between warp and fill direction on the mechanical behavior. The M/L ratio of thread count of 5.5+7.0 specimen is larger than 4.5+4.0 and 5.5+5.0 by 38 % and 41 %, respectively, the corresponding M/T ratio of modulus is larger by 34 % and 29 %, and for strength it is 23 % and 24 %. It is found that the increase of thread count in one direction improves the mechanical properties in this direction but reduces the equivalent elastic modulus and strength in the vertical direction. The simulated stress and strain distribution inside the RUC helps to better understand the influence mechanism of thread count on the mechanical properties of single-ply woven composites.
