I've seen several articles about
this new material over the last week. This one is rather lightweight, but you can find more techie ones if you search for them.
It's supposedly easy to manufacture, but no practical data about how to form it or join it has been published yet. Being a polymer, the first thing that comes to my mind is chemical bonding, i.e., gluing with adhesives, or adhesives combined with rivets. It would be wonderful if it proved practical and economical for builders like us.
Cheers,
