Robert McNees on Nostr: Hydrogen bonding and stacking interactions between adjacent monomer chains in Kevlar ...

Hydrogen bonding and stacking interactions between adjacent monomer chains in Kevlar make it about five times stronger than steel, by weight. It's used in everything from body armor to airplanes to race cars.

I'm a big fan of Kwolek's philosophy of taking time to investigate things thoroughly, even (especially) if they don't work right away or give the expected result.

"If things don't work out I don't just throw them out, I struggle over them, to try and see if there's something there."
