The Discovery of Kevlar

Placeholder — not yet written up. Stephanie Kwolek’s 1965 discovery of Kevlar at DuPont, while investigating high-molecular-weight aromatic polyamides, is the planned first entry here: an accidental, almost-discarded result (an unusually thin, cloudy, low-viscosity polymer solution that most chemists of the era would have poured out) that turned out to spin into an exceptionally strong, stiff fiber. A real bookmarked X post about this discovery has already been identified and is ready to build into a full entry — see Stories for the section this belongs to.
