Conolon-NARMCO Rod

In 1944 Dr. Glenn G. Havens started the National Research and Manufacturing Co. (NARMCO). In 1945, he perfected a technique for producing fiberglass rods. His method used a woven fiberglass cloth and resin known as Conolon, which was wrapped around a removable steel mandrel to produce a hollow blank.
