Özet

Fiber metal laminates (FMLs) are widely used in a wide range of engineering applications, especially in the aerospace industry, due to their superior functional properties and low cost. In this experimental study, hybrid FML composite specimens consisting of five different Al2024/FRP/Al2024 stacked glass and carbon fiber layers were fabricated to investigate the effect of stacking sequences and cutting parameters on the drilling process. The drilling machinability properties of the specimens were investigated by considering the cutting force, torque, surface roughness and damage analyses in the hole after drilling and the results are presented comparatively. As a result of the experimental study, it was determined that the stacking sequences have a significant effect on the machinability. In terms of cutting forces, it was observed that the cutting force increased in carbon stacked areas and the cutting forces tended to decrease in glass stacks. In torque values, there is an increase in glass stacks and a decrease in carbon stacks. The highest roughness values were measured from all-glass stacked specimens. In hybrid composites, it was observed that glass stacks generally increased the surface roughness.
