Abstract
In present days, defence sectors like shipbuilding and aerospace are facing hurdles in developing EM (electromagnetic) wave-absorbing materials. Researchers and scientists focused on developing materials like glass fibre composites, polymer composites and, to some extent, metal matrix composites for the mentioned applications. Polymer-based composites show relatively good shielding against EM waves with the cost of mechanical properties. Metal matrix composites (MMC) in specific aluminium offer high mechanical strength and moderate shielding effectiveness compared to fibre and polymer composites. To use these in intended applications joining is required at some sort of time. The joining technique significantly influences the joint properties and further affects the performance. Researchers mainly focused on developing EM wave materials than focusing on the effect of the joining technique on the mechanical and EM properties of the developed material. In the present work, an attempt has been made to study the effect of the joining technique on the mechanical and EM wave properties of dissimilar aluminium alloys.
