| Abstract | The complete sorption-desorption equilibrium isotherms determined at 23 degrees C indicate that glass fiber- reinforced polymer (GRP) sheets weathered outdoors for 3 years absorb larger amounts of water vapor than the non- weathered sheets. Sorption and desorption kinetic results at 23 degrees C and two levels of relative pressure (p/p[ 0] = 0.80 and p/p[0] = 0.975) show that the weathered sheets absorb water vapor at considerably higher rates than the non- weathered sheets. Larger amounts of sorbed water, and faster sorption and desorption will result in respectively greater magnitudes and higher rates of dimensional changes ( swelling and shrinking). This accelerates the overall effects of environmentally exerted stress-fatigue on the GRP composite. |
