Several approaches for applying high resistance coatings continuously to graphite yarn were investigated. Two of the most promising approaches involved 1 chemically vapor depositing CVD SiC coatings on the surface of the fiber followed by oxidation and 2 drawing the graphite yarn through an organo-silicone solution followed by heat treatments. In both methods, coated fibers were obtained which exhibited increased electrical resistances over untreated fibers and which were not degraded. This work was conducted in a previous program. jg p.5
