Abstract
In order to take full advantage of the tailorability of composite materials, the response of unsymmetric composite laminates is studied in an integrated analytical/ex perimental program. The laminates tested include a symmetric and an unsymmetric layup, [0 2/452] s and [04/454] I , constructed of the IM7/977-2 graphite epoxy material system pro duced by Fiberite. The test conditions simulated mclude both ambient and hot/wet condi tions in addition to tension and torsion. A quasi three-dimensional finite element program is used to evaluate the stress-strain response of these laminates. These responses are com pared with experimental observations.
