test panel No 2.
This one is a 10mm foam core with 1mm carbon skins. So less than half as thick as the previous test panel.
Used my mates lighter car for this test working out about 300kg for one front wheel.

On a brick same as before.

Directly on the kerb.

Proof its a car not just a wheel balanced on the board!!
Virtually no deflection whatsoever and certainly no permenant damage apart from scratches from edge of the brick.
I will run it over with the 4x4 at the end of the week. Although i expect it will get crushed
