Kevlar

A molecular model of Kevlar's hexagonal lattice structure, showcasing its interconnected network of atoms and hydrogen bonds.

A heat-resistant synthetic fiber developed at DuPont in 1965 by the chemist Stephanie Kwolek. Its molecular structure consists of parallel aligned chains cross-linked with hydrogen bonds. Because of its remarkably high tensile strength-to-weight ratio, it became the standard material for ballistic body armor, racing sails, and aerospace composites.
