A problem exists in the operation of electrical equipment if carbon fibers come in contact with critical electrical circuits when accidentally dispersed into the air by a variety of means. The extent and severity of the problem has not been fully evaluated and, indeed, may be overstated. Therefore, there is an urgent need for a comprehensive theoretical and experimental risk analysis that includes all major uses, i.e., aerospace, transportation, and consumer products and manufacturing practices. A Carbon Fiber Study Group was convened to consider whether or not the electrical resistance of carbon fibers could be increased to acceptable levels without altering other desirable characteristics. The group considered 1 the magnitude of resistance changes required to minimize electrical equipment malfunction, 2 whether or not carbon fibers can be modified to meet these requirements, 3 the ease of hardening confined spaces, and 4 the disposal of carbon fibers and composites after use. Conclusions, recommendations, and background information are presented herein. Author
