THE EFFECTS OF WATER ON THE STRENGTH OF LAMINATED PRESSURE VESSELS

Abstract

A series of pressure vessels was exposed to water, 100% relative humidity and humidity cycling both in their 'as wound' conditions and after they had been prestressed to 80% of their bursting load. The resulting final burst measurements were all subjected to a Student 't' test to determine the significance of the effects of water. It appears that a reduction of strength at the 0.95 significance level occurs only to specimens that have been preloaded to 80%, exposed to relative humidity 100% at room temperature for one week, or immersed in water for one week. One month's exposure to humidity cycling does not appear to reduce the strength significantly and there appeared to be no reduction in strength unless the vessel had been previously preloaded.
