[HTML][HTML] Durability of GFRP nanocomposites subjected to hygrothermal ageing
Composites Part B: Engineering, 2015•Elsevier
This paper presents long term durability prediction of 0–5 wt.% nanoclay/vinylester/glass
fibre nanocomposites based on their tensile strength retention in accelerated hygrothermal
ageing using Arrhenius rate model. The specimens were exposed to 30° C, 50° C and 60° C
and 95% relative humidity for 75 days and tested for tensile strength retention as a function
of duration of exposure. The predicted tensile strength retentions for one year of ageing of
vinylester/glass at 30° C, 50° C and 60° C using Arrhenius rate model were 59%, 48% and …

Abstract
This paper presents long term durability prediction of 0–5 wt.% nanoclay/vinylester/glass fibre nanocomposites based on their tensile strength retention in accelerated hygrothermal ageing using Arrhenius rate model. The specimens were exposed to 30 °C, 50 °C and 60 °C and 95% relative humidity for 75 days and tested for tensile strength retention as a function of duration of exposure. The predicted tensile strength retentions for one year of ageing of vinylester/glass at 30 °C, 50 °C and 60 °C using Arrhenius rate model were 59%, 48% and 43% respectively. The corresponding strength retentions predicted for 4 wt.% nanoclay/vinylester/glass were 81.1%, 77.9% and 76.4%. Strength retentions for ten years were predicted using the analytical model to assess their long-term performance.
