Abstract

The experiments of combined laser are carried out for the aluminum alloy and glass fiber reinforced polymer composites. The effects of continuous wave laser and long pulse laser combination, continuous wave laser and short pulse laser combination and timing schemes on the breakdown behavior of aluminum alloy and glass fiber reinforced polymer composites are compared and analyzed. The results demonstrate the plasma impact effect caused by short pulse laser shortens the penetration time of aluminum alloy and dramatically decreases the laser energy required for breakdown based on the thermal softening effect of aluminum alloy caused by continuous wave laser. Nevertheless, for glass fiber reinforced polymer composites, the ablative behavior caused by long pulse laser can further accelerate the breakdown process of composites on the basis of continuous wave laser
