Abstract

The fuel consumption of an aircraft is largely governed by its payload, which emphasizes the continuous demand for advanced lightweight structural materials to enhance the lift-to-weight ratio and improve overall fuel efficiency. Fiber Metal Laminates (FMLs) have emerged as a novel class of hybrid materials that combine alternating layers of thin metals with fiber-reinforced polymer composites, thereby offering mechanical properties superior to those of the individual constituents. Among the different varieties of FMLs, Glass Laminate Aluminum Reinforced Epoxy (GLARE) has been widely adopted in aerospace applications, particularly in fuselage and wing structures, due to its ability to significantly reduce weight while simultaneously improving fatigue resistance, impact strength, and damage tolerance. The present study aims to investigate the mechanical characteristics of hybrid composites fabricated using epoxy resin, bi-directional E-glass fibers, and aluminum alloy with different lamination sequences. To evaluate the performance of these GLARE composites, tensile and flexural tests were conducted under controlled laboratory conditions using a Hydraulic Universal Testing Machine in accordance with standardized guidelines. The experimental investigation focuses on understanding the influence of varying lay-up sequences on the overall strength and stiffness of the composite. The outcomes of this study are expected to provide valuable insights into the optimization of GLARE laminates for aerospace structural applications where weight reduction and superior mechanical performance are critical.

Keywords: Glass, Aluminum, GLARE, Sandwich, Laminate.
