In January 1978, the Department of Commerce issued a news release on the potential for accidental release into the environment of carbon fibers, causing short circuits or other damage to unprotected electrical circuits. A subsequent "Carbon Fiber Study" by the National Aeronautics and Space Administration proposed a coordinated Federal action plan for dealing with potential risks associated with fiber-reinforced composite materials. Carbon fiber composites are increasingly being used in automotive, aircraft, naval, and commercial equipment applications. Carbon fibers are attractive because of their low weight, high modulus, refractory character, and electrical conductivity; they also offer energy savings. On the other hand, carbon fibers are irritating to the eyes and skin, are difficult to incinerate, and are easily dispersed by air movements. Problems experienced and solved in electrical circuits operating in carbon fiber manufacturing environments are discussed for two Union Carbide Corporation operations. Effects observed in the manufacturing plant and adjoining area, types of electrical and dust protection equipment used in the manufacturing process, and preventive maintenance and design and selection considerations are addressed. Processing scrap and end-of-life disposal are also considered.
