摘要：

Composites consisting of a flexibilised epoxy resin, reinforced with woven glass, carbon and polyester fibres, respectively, were soaked in sea water at 10 degrees C and at 20 degrees C. The resulting changes in the mass, modulus and loss factor were monitored for a period of 3 months. All the composites experienced an increase in mass, a reduction in the effective flexural modulus and a corresponding increase in flexural loss factor. The carbon-fibre reinforced material was found to be the least affected. The observed differences in changes in the viscoelastic properties of the glass fibre and polyester fibre reinforced materials were ascribed to different mechanisms of water uptake.
