Building Better Body Armor With Nanofoams
Zothecula writes "Given that scientists are already looking to sea sponges as an inspiration for body armor, perhaps we shouldn't be surprised that foam is also being considered ... not just any foam, though. Unlike regular foam, specially-designed nanofoams could someday not only be used in body armor, but also to protect buildings from explosions."
I would LOVE for them to figure out a better foam for armor for us motorcyclists. Right now we have standard polymer foams in our armor, but I would love some effective stuff that is thinner fill in the non impact points for extra protection. Right now I have thick CE rated foam armor in impact locations that also has kevlar on the outside, but I would love to have a reactive foam for a backboard that is flexible normally but solidifies into a backboard when the texting bimbo in the minivan runs me off the road and I come off the bike.
Current motorcycle armor is effective, but it could be better.
Do not look at laser with remaining good eye.
Nanotechnology... the next big thing.
I'll get my coat
It sure does make for annoying headlines; but 'nanotechnology' is sort of a concept that is doomed by nature to be spread vacuously thin across all sorts of things, both incremental advances and more remarkable stuff.
There probably a material in existence whose bulk properties don't derive from its structure at a fine scale, so the entire history of fields like metallurgy is 'nanotechnology' in a weak sense. On the other hand, though, most of that history, even to the present for economically viable bulk production, is largely messing around with heating and cooling parameters, and throwing various trace impurities into the mix, and then hoping really hard that the right nanoscale structures self-assemble.
The real problem is deciding where to draw the line between 'yeah, it's "nanotech" in the vacuous sense that all materials engineering is' and 'actually "nanotech" in some sense that makes it worthy of the title'...
What do you think the "empty" space in a foam is filled with?
My socks that go missing from the laundry?
