A study of the corrosion fatigue behavior of a graphite/epoxy composite was carried out using compact tension (CT) specimens subjected to combined hydrostatic and axial loading. Such composites are being considered as candidate materials for offshore structures because of their light weight and high strength. Because of the potential application in offshore environments, the behavior of these composites in simulated and actual marine environments is of particular importance. Unidirectional composite specimens with the applied load perpendicular to the fibers, were examined in the as-received and conditioned (distilled water or seawater saturated) state. Specimens were investigated under ambient air, ambient seawater (or distilled water) and high-pressure seawater (or distilled water) conditions. The examination of failure surfaces will be discussed and possible mechanisms for the observed behavior will be offered, in addition, comparisons with the behavior of similar composites examined using other test procedures will be made.
