The equations of equilibrium of a composite plate within-plane fiber waviness are derived and the effects of waviness on the buckling loads are studied. The plate is assumed to be in cylindrical bending and the resulting eigenvalue problem is solved using a combination of a shooting algorithm and the secant method. A numerical example of a plate with sinusoidal fiber waviness shows that the buckling load decreases as the amplitude of the waviness increases. However, results indicate that it is possible to enhance the stability characteristics of the plate by introducing artificial fiber waviness to increase its buckling load.
