Abstract
In this study, bending and transverse shear properties of plain weave fabric composite laminates are investigated through the finite element analysis considering the intra-lamina inhomogeneity due to the weave architecture of constituent yarns. Using the homogenization method, the effective Reissner-Mindlin plate stiffness of the composite laminate is calculated. Then, the effect of the number of plies on the laminate bending elastic modulus and the transverse shear modulus is evaluated. For the bending property, the experimental evaluation is also conducted to validate the numerical analysis. Through the numerical and experimental investigations, it is found that in case the number of plies is large (eight-plies or more), these moduli are constant independent of the number of plies, however in case the number of plies is very small (three-plies or less), these moduli significantly decrease.
