Thermomechanical Analysis of Water Aged Pultruded Composites

Excerpt: Water absorption behaviour of pultruded fibre reinforced plastic (FRP) composites has been investigated in this study. Three resin systems were evaluated in distilled water and salt-water environments. The effect of water absorption on dynamic mechanical properties of the composite was analysed. Results indicate that rate of water absorption was the lowest for the vinylester and the highest for the polyester composite.
