A simple and accurate method for estimating the three-dimensional effective moduli of symmetric and orthotropic laminated composites is presented. The method is based on obtaining the exact displacement field of three boundary value problems of laminated composites using the Airy stress function solution technique. The effective moduli are estimated by matching the boundary displacements of the equivalent homogeneous system with those of the laminated system. Among the estimated effective moduli, those associated with the interlaminar direction are of special interest. It is found that the effective interlaminar normal stiffness in extensional deformation is independent of laminae stacking sequence which is consistent with the finding of Pagano (1974). However, the laminate interlaminar shear stiffness is dependent on stacking sequence, and it is shown that the rule of mixtures can not predict the interlaminar shear stiffness accurately.

Strength And Stiffness

Composite materials are mostly submitted to dynamic loads, because of their excellent specific strength and stiffness, therefore the resonant technique is adequate for the determination of stiffness properties. Three plates of similar carbon-epoxy composites with distinct fibre orientations were studied with this technique. The effect of stacking sequence on the rigidity of laminated composites was investigated A significant influence of this material parameter on in-plane elastic properties was found, allowing optimization of stiffness for a particular application.
