Abstract
In this study, Fibre Metal Epoxy Laminates (FMLs) are considered and are tested for their bearing response: Carbon Reinforced Aluminium Laminate (CARALL) with carbon and aluminium and Carbon Jute Reinforced Aluminium Laminate (CAJRALL) with carbon, jute and aluminium, formed by replacing a portion of carbon in CARALL by jute. This work investigates the effect of addition of natural fibre, jute, in CARALL FML on its pin type bearing performance, for different e/D ratios, W/D ratios and Stacking Orders and the influence of these parameters on bearing load and failure mode are also assessed. It is noted that the increase in e/D and W/D ratios and stacking arrangement of materials in the FMLs have significant effect on the ultimate load capability of the pinned joint. It is inferred from the experimental study that the CAJRALL laminate which is of low weight, lesser cost and more environment-friendly, withstands appreciable bearing loads and hence can be ideally suited for construction of structures like storage silos.
