Impact Attenuator

[Henrique]

Hello, we are starting a new project with type monocoque chassis, I wonder what alternatives for creating the impact, until then wore radiator (aluminum) but saw that some teams use foam and others.
Any idea will be welcome.
Sincerely,
Henrique.

What was that team at FSAE West with the large OD aluminum tubing as an IA? It looked brilliantly light compared to a honeycomb or brick.
