Experimental Evaluation of Adhesive Characteristics of Bonded Rolled Steel Section With Basalt Fibre Reinforced Polymer

Adhesive bonding is widely embraced method for the act of uniting materials in various industries, including aerospace, automotive, construction, and electronics. Peel test is a type of mechanical test that is widely utilized to evaluate the strength and quality of adhesive bonds. This paper experimentally examines the bonding strength between mild steel section and basalt fibre bonded with epoxy resin peeled with the help of UTM. This test is performed for various adhesive combination. As the bottom adhered is hard and the upper adhered is flexible, the 90° peel test is utilised. The average bond strength of the specimens utilizing blue fix resin was determined to be 15.5 MPa. In contrast, the mean bond strength for the specimens incorporating Araldite epoxy resin was found to be 21.2 MPa, while the use of polyester resin yielded a strength of 17.1 MPa. As observation of results there is 26.88% more strength gives Araldite epoxy resin to blue fix hardener while considering the bonding strength by peel testing and 19.33% more strength with polyester resin. More resins like Vinyl Ester Resin, Cyanoacrylate Adhesive, Methacrylate Adhesive, Urethane Adhesive and Acrylic Adhesive are available for bonding. The predominant failure mode observed in the specimens was cohesive failure within the adhesive layer. It was discovered that the surface preparation significantly affected the bond strength, with smoother and cleaner surfaces producing stronger bonds. The results indicate that Araldite Epoxy Resin offers excellent flexural strength, making it well-suited for applications requiring high stiffness and load-bearing capacity.
