1 Float zone refining of silicon 1955 E.I. du Pont de Nemours & Company (originator) This physical research chemist at DuPont's Experimental Station is using an analog computer to determine temperature characteristics of a bar of silicon undergoing refinement by the floating zone technique which involves gradual moving of the silicon through a furnace so that a small part of the bar is molten at a time. Research such as this on an existing product is required to maintain the company's position in the highly competitive chemical industry.

2 DuPont laboratory team discussing results of an experiment 1955 E.I. du Pont de Nemours & Company (originator) The industrial chemist today stands in sharp contrast with the lone wolf inventor common even a little more than a generation ago. Although the initiative and creative thought of the individual is still of prime importance, the modern researcher is a team player with a strong sense of cooperative effort. Pictured here is a DuPont lab team discussing results of an experiment.

11 Interview with Don Sturgeon, 2014 July 30 2014-07-30 Sturgeon, Don (interviewee), Smith, John K. (John Kenly), 1951- (interviewer), Oates, Mike (videographer), 302 Stories, Inc. (production company), Eleutherian Mills-Hagley Foundation (originator) Donald Sturgeon details his work at DuPont evaluating the properties of Kevlar fibers, particularly for their utility in composite structures. He recounts that while the fiber was incredibly strong in tension, it had relatively poor performance in compression. The peculiar features of Kevlar fibers required that Kevlar reinforced products had to be carefully engineered. Initially, DuPont hoped that Kevlar would find a large market as tire cord. When tire manufacturers opted for steel belts in...

Donald Sturgeon details his work at DuPont evaluating the properties of Kevlar fibers, particularly for their utility in composite structures. He recounts that while the fiber was incredibly strong in tension, it had relatively poor performance in compression. The peculiar features of Kevlar fibers required that Kevlar reinforced products had to be carefully engineered. Initially, DuPont hoped that Kevlar would find a large market as tire cord. When tire manufacturers opted for steel belts in radial tires, DuPont had to find other markets for Kevlar.

Sturgeon further describes his work in developing novel applications for Kevlar. Because Kevlar was difficult to make and process, DuPont had invested an unprecedented $500 million by the mid-1970s. Instead of one large market, DuPont had to develop many smaller applications for Kevlar. Sturgeon worked on developing and promoting weight-saving Kevlar composite materials to the aircraft industry. He was also involved in developing bullet-proof vests and non-cut fabrics. Through these extensive product development and marketing efforts, Kevlar eventually became a profitable product.
