The behavior of one-ply and two-ply laminated cord-rubber composite plates in uniaxial tension is presented. The plate mechanical properties are presented as functions of cord angle for various cord-modulus to matrix-modulus ratios. The model developed takes account of the extension-twisting coupling of the cord, as well as the exact location of the cord within the composite plate. An energy method formulation is used, and the model is solved using the Ritz method. The current results are compared to classical lamination theory results to show the limits of usefulness for classical lamination theory for this class of composites.
