Abstract : A survey was conducted of available long-term strength properties of fiberglass-reinforced plastic structures. Included are fluid containment vessels, marine structures, and aircraft components with up to 19 years of service. Correlations were obtained for the variation of static fatigue strength, cyclic fatigue strength, and residual burst strength for pressure vessels. In addition, data were presented for the effects of moisture on strength retention. Data variations were analyzed, and relationships and implications for testing were discussed. Change in strength properties for complete structures was examined for indications of the effects of environmental conditions such as moisture and outdoor exposure (ultraviolet radiation, weathering) on long-term durability.
