Investigation of Tensile and Bending Behavior of Aluminum based Hybrid Fiber Metal Laminates

Present investigation was focused on the effect of strain rate and lay-up configuration on tensile and flexural behaviour of four combinations of fiber metal laminates. Tensile and flexural tests were conducted on universal test machine as per standards. The result shows that the tensile strength increased with increasing strain rate. However the flexural strength decreased with increasing strain rate. Both tensile and flexural strength are maximum for carbon based FML structures, minimum for glass based FML and hybrid FML structure lies between them. The observations on both tensile and flexural failure mechanisms deduced from a microscopic study of the fractured specimens are presented.
