Microscopic images of damage in the composite panels with the hybrid reinforcement are shown in Figure A2. The jagged fragments of the fibers at the side opposite to the impact side are the result of the cutting process.

**Figure A2.** Cross sections of the damage formed in the composite panels after impact of the striker: (**a**) conical, (**b**) hemispherical, (**c**) blunt, (**d**) ogival.
