Experimental And Numerical Analysis of Impact Strength of Fiber Metal Laminates Made of Aluminium with GFRP

The benefits of fiber-reinforced matrix systems and metallic materials are combined in fiber-metal composite technology. The usage of fiber metal laminates is a result of the growing need for lightweight materials. In our work, fiber metal laminates are created utilizing aluminum-6061. Glass fiber that is single, double, or triple layered is bonded using the hand layup process and Epoxy-LY556 and Hardener-HY951. In this work, a single layer, double layer, and triple layer GFRP specimen made of aluminum, glass, and epoxy fiber metal laminate (FML) was created in accordance with ASTM D 7136 standards. A low velocity impact testing equipment was used to examine the impact behavior of specimens made of aluminum, glass, and epoxy fiber metal before experimental findings were obtained. The experimental results demonstrate that the impact strength of the composite will change as the number of GFRP layers increases. Utilizing ANSYS software and the ACP Pre post and Transient Structural Analysis Method, another numerical simulation was carried out. ABACUS analysis was used for material optimization, and the outcomes of the model and optimization were compared in order to validate the suggested numerical model. Due to its strong strength and low density, FML is frequently employed in the aerospace industry and wind turbine blades.
