Analytical and Experimental Investigation of Adhesive Bonded GFRP Nano Composites and M.S Girders

Abstract

As the application has huge demand in Fiber reinforced polymer (FRPs) composites, they have been applied in a many application like aero modeling, automotive, ships and constructional work. GFRP has Omni-potential properties such as in specific strength, in specific stiffness, with good damping, less thermal expansion, great dimensional stability, design flexibility, etc. A great deal of work has been done already which discuss about the mechanical behavior of glass fiber reinforced polymer composites based on ASTM (Plastic) standards. Against this background, the present research work has been undertaken with the aim, to find out both the physical and mechanical behavior of GFRP based on ASTM (Composite) standards. The objective of the present work is to study about the physical and mechanical behavior of GFRP composites. Also this work includes the investigation of the behavior of adhesively bonded GFRP composites with steel girders. In this work E-glass fiber is used as reinforcing agent with the epoxy matrix. GFRP composites are fabricated by both Pultrusion and Sheet molding compound process. This research work results in comparing the values of testing of GFRP composites by both the ASTM standards, the best suited adhesive for bonding of composites is selected based on the results. Also the behavior of adhesively bonded of GFRP composites with steel girders is experimentally studied.
