Abstract
Glass fibre reinforced plastic (GFRP) composites are being used in a large number of diverse applications ranging from aerospace to sports equipment. The reinforcement materials are highly hygroscopic nature; the matrix material provides protection to the reinforcement. The products made of composite materials are exposed to different environmental elevated temperatures conditions, water molecules travels along the reinforcement. This leads damage to the interfacial bonding and affects the performance of the composite laminate products. It is necessary to perform mechanical and environmental characterization to enhance their application spectrum. There is need to investigate the mechanical behavior of the composite laminates, when subjected to different environmental conditions at different exposure schedules. The aim of the present work is an attempt to provide the investigation procedure to assess influence of moisture absorption on strength degradation at different temperatures coupled with life cycle time schedules. From the results and mathematical analysis, it was clear that the tensile behavior of the salt water conditioned specimens were significantly reduced.
