【 摘 要 】

In the present study effect of artificial sea water environment on mechanical properties of glass/polyester composites was investigated. The laminates fabricated by using vacuum bagging method, were characterized for moisture absorption in artificial sea water for an immersion period of 60 days. Degradation of mechanical properties of aged composites were examined through tensile, flexural, hardness and impact test. The results revealed that long term absorption of sea water reduces the mechanical property of the glass/polyester composite. Rate of degradation of mechanical properties of laminates shown higher trend during earlier days of immersion in sea water and the rate slows down as the immersion period increases.
