Abstract : This report summarizes research done under the project, 'Fracture Mechanics of Fiberglass Reinforced Plastic Composites Suitable for Hull Materials,' which was completed in June 1975. The study was divided into three areas: (1) the effects of material and geometric variables, time and temperature on the fracture toughness of the fiberglass laminates; (2) cyclic fatigue crack propagation; and (3) marine environment effects. In each case, the mechanisms of fracture in fiberglass-hull materials have been studied with a view toward preventing catastrophic failures. (Author modified)
