pchapman 279 #4 January 31, 2015 Cool. I don't know about the weight and how it compares to more conventional steel plate and such. In tank armor they have been playing with and using ceramics for decades, sometimes using armor with multiple layers of material of different densities to disrupt the path of a projectile. Some interesting ideas though, to use loose rather than fixed armor elements. Quote Share this post Link to post Share on other sites
BleuCiel 0 #5 January 31, 2015 pchapmanSome interesting ideas though, to use loose rather than fixed armor elements. I guess with fixed armor plates that if a 2nd shot hits in the same spot as a previous shot, then it stands a much better chance of penetrating. But with these loose spheres, when a bullet hits in one place, more spheres just drop down into place to replace the void created by whatever damage occurred. So there is always a fresh supply of new spheres to take subsequent shots, even in the same place. So I think its not just the impact absorbing effects of the ceramic spheres, but also the way they're stacked to allow gravity to fill any voids.

champu 1 #7 January 31, 2015 For fixed/structure applications I'm curious how it stacks up (har har) against a sandbag wall in terms of cost/performance. Quote Share this post Link to post Share on other sites
