As composite materials become more attractive for use in large naval structures, an understanding of the mechanical behavior of composites having a thickness greater than 6.4 mm (0.25 inches) becomes imperative. In this test program, a compression test fixture that allows the testing of composites up to a one-inch thickness and greater was designed and refined. This fixture was used to evaluate the effects of constituents, fiber orientation, and thickness on the compressive response of composite materials. In addition, the fixture was used to determine whether the failure mechanisms observed for thick composites are similar to those that have been observed and reported for composite materials less than 6.4 mm (0.25 in.) in thickness. The strength, stiffness, and failure characteristics of 48 ply, 96 ply and 192 ply carbon/epoxy and S2 glass/epoxy composites are discussed. Unidirectional and (O/O/90) style laminates are also investigated.
