Abstract
Water absorption by glass fibre reinforced epoxy resin and its influence on tensile strength have been studied and the role of the resin hardener shown to be very important. All tests were conducted under conditions of relative humidity ranging from 0% to 100% RH and in the temperature range 25°–90°C. It was found possible to apply diffusion theories to those materials for which diamine and dicyandiamide hardeners had been used but not when an anhydride hardener had been employed. Damage, as revealed by a fall in tensile strength, was found to occur at relative humidities greater than 60–70% RH. It was seen, both under humid conditions and in immersion tests, that this damage was not related to the quantity of water absorbed by the composite but to the temperature and time of exposure after the water concentration limit was passed.
