Using laser-accelerated Al flyers, we examined hyper-velocity impact tests of CFRP (carbon fiber reinforced plastics) laminates as a simulation of orbital debris impact. A short-pulsed intense laser beam can accelerate a small flyer as fast as LEO (low earth orbit) satellite velocity. We succeeded in observing the deformation and fracture processes of the CFRP targets with a high-speed framing camera. When the pulsed laser was set the single shot energy of 26.4 J. corresponding to Al flyer velocity 8.3 km/s, we observed that the fiber breakage at the back surface of the CFRP target occurred at about 500ns after the impact.
