    bad idea. corrugate yields under load in a much different manner than expanded foams do. corrugate doesn't deform under load until within about 5-10% of its maximum strength. up until that point it just transfers the load without absorbing any of it.

    that, and the fact that it is designed as ribs is another major flaw. the point of a helmet is to dissipate and absorb impact force. by using ribs instead of a vented shell, you're drastically decreasing the surface area, which in turn concentrates the impact force in the areas of contact.

    Perhaps a empty bucket and a can of expanding spray foam insulation?
