Mechanical Advancements in Fiber Metal Laminates: Experimental Study on Aluminum Mesh-Reinforced and Aluminum Sheet-Reinforced Kevlar Fiber Laminates for Structural Applications

Abstract

Fiber Metal Laminates (FMLs), are utilized across various applications because of their important benefits, which include high impact resistance, low density, and high strength to weight ratio. In the current work, thin layers of metal sheets and Kevlar fiber are stacked in a progressive manner to create functionally graded FMLs. Aluminum wire mesh-reinforced Kevlar fiber is fabricated through hand lay-up, with a focus on examining mechanical properties like tensile strength and flexural strength for potential structural applications. All tests adhere to ASTM standards. The results reveal that, in comparison to Al sheet Kevlar fiber composite materials, aluminum mesh-reinforced Kevlar fiber-reinforced polymer (KFRP) exhibits greater tensile and flexural strength, effectively sustaining applied loads. The tested specimens unequivocally indicate that the inclusion of wire mesh of Aluminum metal changes the mechanical properties of Kevlar composites.
