Degradation of fatigue resistance of filament wound glass fibre reinforced/vinyl ester pipes exposed to aqueous environments

Abstract

In this contribution, the author reports the effect of salt spray and oxygenated salt water immersion and 100% relative humidity conditions on the fatigue resistance of filament wound glass fibre reinforced/vinyl ester thermoset pipes. Exposure to salt spray and oxygenated sea water immersion for periods of up to 10?000 h produced varying degrees of degradation in the fatigue resistance of glass fibre reinforced plastic pipes. The most severe degradation in fatigue resistance was observed at an exposure of 300 h under salt water spray condition and at 10?000 h of exposure under oxygenated salt water immersion condition.
