    Abstract

    Glass-fiber-reinforced laminates composed of two different commercial epoxy resin matrix formulations, a “medium-temperature” system and a “high-temperature” system, were tested in tension after immersion in hot water. Tests were carried out both in the “as-is” wet condition and after drying. The internal moisture condition was found to have a significant effect on the tensile strength. Dried specimens of the medium-temperature resin were stronger than their wet counterparts. The reverse was the case with specimens based on the high-temperature resin.
