Process for carbon-coating silicate glass fibers

摘要

This invention is a strand of silicate glass fibers with a carbon skin or sheath around each glass fiber of the strand. The invention uses hydrocarbon pyrolysis with silicate fiber glass manufacturing to produce fibers using conventional melt-bushing technology. The formation of a carbon skin or sheath on the silicate glass fibers offers numerous advantages. For example, pyrolyzing hydrocarbons is endothermic. Heat is removed in the process and fibers are cooled faster. This helps to achieve higher throughput.
