Study the Effects of Environmental Factors on Glass Fibre Reinforced Polymer Composites

Composite material consists of assemblage of two materials of different nature .Composite materials are used in industries because of its high strength to weight ratio and lighter in weight such as aerospace, automobiles, marine, architecture etc .Carbon fibre-reinforced polymer and Glass fibre-reinforced polymer (GFRP) are composits Glass fibre-reinforced polymer (GFRP) have been used as an alternative to steel in concrete due to high strength- to-weight ratio, high stiffness-to-weight ratio, and corrosion and fatigue resistance. GFRPs have been found attractive in the Asian region due to their cost competitiveness .The environmental factors for the deterioration of GFRP are temperature, sunshine, water, moisture etc. For the achieving the objective an experimental setup was prepared. The aim of the experiment was to study the combined effect of chosen parameters moisture, alkali and temperature & also to study the rate & magnitude of damage of GFRP composites. By experimental observations ,it was concluded that reduction in tensile strength is considerably large (about 85 to 90%) in the almost all the samples immersed in the aqueous NaOH. While there is marginal reduction in the strength of the samples immersed in water as compared to initial samples. The trend of reduction in water bath is as per expectation, which shows 10-20% reduction in first month and 30-40% reduction in second month..
