polystyrene foam on the other hand might do the trick
Would this be a good material for aviation?
A lot of foamy materials are indeed used for that purpose
Why weren't other materials tested? Brick, concrete, woods?
Did they use cardboard derivatives?
Have you considered fibre reinforced plastic? I'm not an expert but I'm curious if that's a good option.
I wonder if such a thing is possible with modern materials?
What about using plastic or some flexibly epoxy. Would it have some adverse effect or is there a cost issue?
Why not use other materials?Modified acrylic or compact laminate?That will save lives.
I wonder why they didn’t try a pdms resin as wellhere’s the paper: https://www.nature.com/articles/s41586-024-07061-4.pdf
