N2 - The previously developed [1 - 5] Boeing Co. Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) concept is subjected to optimization designer material protocols [6 - 17] in order to obtain the best combinations of fiber orientation, number of fibers, stacking sequences, volume fractions, fiber and matrix, material properties, etc. The general elastic and viscoelastic designer material/structures theory was developed in [15] and specialized to PRSEUS type composites in [6] and [7]. In the present study, a composite rectangular plate is analyzed under the influence of external aerodynamic loads (lift) and internal loads (cabin pressure) leading to bending and in-plane loads.
