2. In other tests 5052-0 and 2024-T6 alloys of aluminum were compared when used as the simulated honeycomb material. Again, no difference in impact damage was observed on the backup sheets. As long as the honeycomb wall has strength enough to make it useful as a wall filling material of structural value, it will have the ability to channel debris from impacts equivalent to those simulated in these tests
