Abstract

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) before testing in water. The results show that water significantly reduces the fatigue life at low loads but not high loads. Moreover, preconditioning had no effect on fatigue life in water. Consequently, using higher loads or preconditioning to accelerate fatigue tests in water is not a useful approach.
