This research project is part of a multidisciplinary effort to determine the long-term durability of continuous fiber, polymer matrix composite structures exposed to ambient and elevated temperature and moisture conditions in a marine environment. The project has two main objectives: first, to determine the feasibility and a methodology for prediction the long-term behavior, and consequently the durability, of these composite systems by combined theoretical and experimental means; second, to carry out and complete a characterization on two theme materials so that other researchers can implement this information in their structural and damage analyses. This project addresses in-part both of these issues.
