- Abstract
In the Fibre Metal Laminate (FML), Carbon Reinforced Aluminium laminate (CARALL), aluminium is placed next to carbon fibres. The potential difference between the aluminium and carbon is larger, leads to galvanic corrosion, which tries to bring down the durability of the FML. To bring down the effect of corrosion, a material layer is introduced between fibres and aluminium so as to separate them thus lowering the possibility of occurrence of corrosion. Another approach is to coat the surfaces of aluminium with different proportions of aluminium oxide nano particles prior to fabrication of the FML. For both the cases, corrosion rates and polarization resistances are determined and compared. In addition, the surface morphological studies were carried out using SEM to reveal the intensity of corrosion. The electrochemical results revealed that the jute reinforced CAJRAL FML and CARAL FML coated with 10% alumina has better corrosion resistance compared to other FMLs.
