Interview with Don Sturgeon, 2014 July 30
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. [ID:
