Carbon Fibers for Electrically Heated System
Characteristics of fibrous carbon materials and techniques for fabricating them into electrically heated systems have been investigated. The inherent characteristics of carbon fibers, yarns, and fabrics and make of composites of carbon with glass fibers have been evaluated by analytical and experime...
