created high-performance carbon fibers at the Union Carbide Parma Technical Center, now GrafTech International Holdings, Inc., located outside of Cleveland, Ohio. Bacon's breakthrough Those fibers were manufactured by heating strands of rayon until they carbonized (carbonization). This process proved to be inefficient, as the resulting fibers contained only about 20% carbon and had low

strength and stiffness properties. In the early 1960s, a process was developed by Dr. Akio Shindo at Agency of Industrial Science and Technology (National Institute of Advanced Industrial Science and Technology) of Japan, using polyacrylonitrile (PAN) as a raw material. This had produced a carbon fiber that contained about 55% carbon. defunct 1980 location_city Cleveland, Ohio location_country United States '''White Motor Company
