1 Interview with Ted Merriman, 2015 December 4 2015-12-04 Merriman, Ted (interviewee), Smith, John K. (John Kenly), 1951- (interviewer), Oates, Mike (videographer), 302 Stories, Inc. (production company), Eleutherian Mills-Hagley Foundation (originator) After describing his education and early work at the DuPont Savannah River plant, Merriman describes his first project at the Pioneering Laboratory at DuPont Experimental Station in Wilmington in 1969 working on new uses for ceramic aluminum oxide fiber PRD-29. Merriman then details his role in developing a pulped form of Kevlar fiber that made it suitable for use in automobile brake lining in the late 1970s, after it was discovered that the standard material, asbestos fiber, caused a particular form of lung cancer. Merriman developed a process that produced Kevlar fluff using conventional paper-making equipment. Because Kevlar cost about one hundred times as much as asbestos, brake linings had to be redesigned to use very small amounts of it. Working with brake pad manufacturers, Merriman succeeded in producing a commercially viable Kevlar brake pads that had good wear characteristics and were quieter than other types. Brake lining became a significant market for Kevlar. Merriman also describes the extensive testing on Kevlar that DuPont performed at its toxicology facility, the Haskell Laboratory, to ensure that Kevlar did not have adverse health effects.
