Hexcel Corp /de/
A maker of lightweight carbon fibers, prepregs, honeycomb, and resins sold under brands like HexTow and HexPly, used in commercial jets, military fighters, and industrial parts. It began in 1948 as California Reinforced Plastics, founded by two World War II veterans building "expanded honeycomb" in a Lafayette basement, and took the name Hexcel in 1954 after the hexagonal cells of its core product. Its honeycomb made the landing pads that cushioned Apollo 11's touchdown on the moon in 1969.
