Abstract
The influence of an applied stress on the solubility and diffusivity of aqueous hydrochloric acid in polyester resins has been examined. A radioactive tracer method, involving the use of3H and36Cl, enabled the mobility of both the water and the acid in the solution to be followed simultaneously. The results obtained were in accordance with those obtained previously with unstressed resins and showed that whereas water would diffuse freely in stressed polymers, hydrochloric acid would not. The results have important implications in relation to the mechanism of crack propagation in E-glass/polyester composites.
