Effect on Vibration Characteristics of Fiber Metal Laminates Reinforced with Jute/glass Fibers

Fiber metal laminate has outperformed aluminum alloys and fiber-reinforced polymer composites due to its superior mechanical characteristics and reduced density. They are commonly employed in aerospace applications. This paper investigates the damping capacities of fiber metal laminates, including stainless steel, glass fiber, and jute ply, as well as their virgin counterparts. The hand layup method is used to create laminates with eleven plies, which are subsequently compression molded. The plies are held together by epoxy adhesive. Tensile strength, modulus, and damping properties of composite laminates are all tested. The damping ratio and modal frequencies are also determined using experimental modal analysis. The influence of hybridization is investigated for modal and damping parameters obtained from damping experiments under fixed-free boundary conditions. The results of the experiments show that as the free length increases, the modal frequency decreases. The bigger the number of jute pies at the extreme ends, the better the damping properties. These compositions have a greater damping ratio as compared to other configurations.
