Mechanical and Machinability Characteristics of Fiber Metal Laminates

The objective of this book was investigated to evaluate mechanical and machinability characteristics of Glass-fiber-Reinforced Aluminium (Glare) laminates as well as Aluminium sheets of same thickness. In addition to that the tensile and flexural strength of Glare laminates were compared with values of aluminium sheets. In this project, the aluminium based FMLs were fabricated using hand layup technique and cut as per ASTM standards. Three types of layers such as 2/1 Glare, 3/2 Glare and 5/4 Glare laminates were prepared. Computer controlled UTM machine used to determine the tensile, flexural properties and failure mode of the Glare laminates and Plain aluminium sheets with same thickness. From the test results the graphs were plotted for load vs displacement, tensile and flexural strength vs layers thickness. It shows that tensile and flexural strength of Glare laminates purely depend on the volume percentage of fibre and it exhibits improvement over the properties of aluminium sheets. Then evaluate the cutting parameters (cutting speed and feed rate) and the influence of the fibers under delamination factor.
