Drilling on Fibre-Glass Composite using CO2 Laser
Fibre-glass composite has been increasingly used in automotive, aerospace and electronics industries, where hole making on this material is a major process. In this paper, non-traditional machining method was employed to drill the fibre-glass composite sheet of 2 mm in thickness having four layers...

| description | Fibre-glass composite has been increasingly used in automotive, aerospace and electronics industries,
where hole making on this material is a major process. In this paper, non-traditional machining method was
employed to drill the fibre-glass composite sheet of 2 mm in thickness having four layers of glass-fibre with
orientation <0, 90, 0, 90>. The machining setup consists of computer-controlled laser source and air supply by a
compressor that acts as assist gas for cooling. The type of laser source was CO2 with a maximum power of
30W. The machining parameters under consideration were laser power and pulse duration. A total of 12 holes
were drilled varying laser power and pulse duration. Laser power was varied from 15 to 25W while pulse
duration from 2 to 5 minute. Laser-drilled holes were investigated under optical microscope. The hole quality
was evaluated with the hole size, hole geometry, burn mark and heat-affected zone. Hole quality were then
compared for each parameter combination. It was found that the laser power had predominantly affected the
quality of the hole in fibre-glass composite material during laser-drilling. |
