EFFECT OF ENVIRONMENT ON UNIAXIAL COMPRESSIVE FATIGUE PERFORMANCE OF GLASS FILAMENT REINFORCED PLASTIC LAMINATES.
Abstract
Uniaxial compressive fatigue performance is presented for wound flat plate laminates incorporating the E787 Resin System and reinforced with S994 Glass Cloth (Type 143), S994 Glass Roving, and PPG Hollow Glass Roving. A total of five conditioning and testing environments were imposed on specimens from the three laminate constructions. These included specimen tests: dry, no preconditioning; dry, after 500 hours - 10,000 psi water exposure; in water at zero pressure, no preconditioning; in water at 10,000 psi, no preconditioning; and in water at 10,000 psi, after 500 hours - 10,000 psi water exposure. Fatigue curves generated from specimen tests of the three laminates under the above environments are presented. Relative laminate performance is discussed and environmental effects are compared based on these curves. Equipment developed for performing specimen fatigue tests in air is described. The modification made to that equipment which permitted fatigue testing to be performed in the pressurized water environment, is also presented. (Author)
