Abstract
It is known that the long-term strength of a glass fibre composite can be significantly reduced when the composite is exposed to high stresses in the presence of water. Resin properties such as heat deflection temperature and tensile elongation are shown to affect composite lifetime under conditions of sustained stress at various temperatures in an aqueous environment. The measurement of time to failure of unidirectional glass fibre reinforced composite rods containing E-glass fibre strands and one of a series of isopolyester resins suggested a correlation between stress, time to failure, and the temperature differential between the resin heat deflection temperature and the exposure temperature. Such correlations were established, and it was found that time to failure decreased significantly at moderate relative stress as the temperature differential (HDT-exposure temperature) became less than 10 degrees C. 13 refs.
