Kevlar Was Nearly Discarded. One Woman Fought to Prove It Could Save Lives
On this episode of Our American Stories, Kevlar is now a staple of body armor, trusted by law enforcement, military personnel, and first responders, but when Stephanie Kwolek first developed the fiber in a DuPont lab, it was almost thrown away. The material didn’t behave like others, and no one saw…
Materials Science: From Silly Putty to Self-Healing Robots
A failed rubber substitute. A cloudy liquid that looked like a mistake. A robot that heals itself.
This episode looks at three chapters in Carnegie Mellon University's long history of materials science: two born from happy accidents, and one built entirely on purpose.
The first is Silly Putty. In t…
