The usage and replacement of conventional materials with polymer composite materials for engineering applications is always questioned by the end user, unless otherwise the research oriented reliable supporting certification is made available. Fibre reinforced polymer composites are being used replacement material in various applications like marine boats aerospace, military and renewable energy generation. The reinforcement materials are highly hygroscopic nature and exposed to environment, water molecules travels along the reinforcement and affects the performance of the materials. In the present work an attempt has been made in establishing the investigation procedure to assess influence of moisture absorption coupled with temperature. And to estimate life cycle time of polymer composite components such as marine boats and submarine applications and under water applications. The results of the experimental investigation showed that the GFRP Composite laminate tested in different environmental condition under tensile loading. From the experimental results and numerical analysis, it was clear that the tensile behavior of the salt water conditioned specimens were significantly reduced. The results of the analytical predictions and numerical simulations are in good agreement with the experimental results.
