Experimental Study of GFRP Butt Joint For Aluminum & Mild Steel Adherents Under Flexural Load

In our day-to-day living, we come across parts which are joined together. When parts take up the load, often the joint becomes the weakest link. This means that the strength of the joint is less than that of the parent components. Due to which, glass fiber reinforced plastics (GFRP) play a vital role in many engineering applications as an alternative to various heavy exotic materials. In this study, a series of GFRP butt joint were formed between two different adherent pipes of outside diameter 25.4 mm, inside diameter 22 mm and 175 mm long. The type of information to be derived is appropriate to study the flexural behavior of Aluminum and Mild Steel pipes reinforced with GFRP butt joint in terms of serviceability limit states requirements. The proposed bond model was established by calibrating the parameters of grade UA473 glass fiber sheets (preselected fiber angle +10° and -10° alternatively) by varying number of joint layers using the experimental results of four point bending tests carried out by the authors, taking into account the experimental bending moment versus extension. The study investigated that that aluminum pipe when adhered along with GFRP composite, the bending moment to bear exceeds as compared to aluminum pipe alone.
