The Effects of Water on the Fatigue Behavior for Pultruded Glass-Reinforced Composite
Kate Liao, Carl R. Schultesiz, Donald L. Hunston, L C. Brinson
Pultruded composites are finding increasing use in infrastructure and marine applications where they see prolonged exposure to environmental factors such as moisture. This work examines the fatigue behavior (4 point bending) in air and water for pultruded materials. Some specimens were preconditioned in water for 6 months (room temperature). The results show that water significantly reduced the fatigue life at low loads but not high loads. Consequently, using higher loads to accelerate the test is not a possibility. Preconditioning in water had no adverse effect so both load and water were required to see degradation for the conditions tested here.
