Abstract : The effect of humidity cycling on the tensile strength of single E-glass fibers coated with epoxy resin are reported for cycling periods up to five days. Experiments to study the effect of fiber tension during resin cure were initiated and stress rupture tests at room temperature are reported. Based on the large deflection theory of a homogeneous plate by Von Karman and the small deflection theory of asymmetrically laminated anisotropic plates by Stavsky and McGarry,A LARGE DEFLECTION THEORY OF ASYMMETRICALLY LAMINATED ANISOTROPIC PLATES WAS DEVELOPED. The transverse shearing stresses and the stress normal to the plane of the plate could be computed from the governing differential equations and macroscopic equilibrium equations. To satisfy the loading conditions at the top and bottom surfaces of the plate three linear differential equations were obt ine in addition to the eighth order system of nonlinear governing differential equations.
