Drill-Ability Studies of Laser Drilled Micro Holes on CFRPComposites

This paper begins with the introduction on composite materials and their production techniques. It further describes, the experimentation concerned with fiber reinforced polymer (FRP) composites where high strength reinforcing fibers are combined with polymer (plastic) matrix for achieving suitably high strength. The machinability of the CFRP is of the major concern with surface finishing of the order of micro-scale. The analysis of FRP laminates is based on the micro drilled holes by laser drill and the result so obtained is analyzed through scanning electron microscope (SEM). The consideration of the heat accumulated zones as a result of laser drilling is analyzed. The suitable parameters for obtaining a good surface finish with the least amount of heat accumulated zone by laser drilling on the Carbon Reinforced Plastics concludes the paper
