Apparatus for increasing the breaking strength of glass fibers |
摘要 |
The breaking strength of glass fibers, such as generally utilized in optical communication techniques, is materially improved by subjecting a glass fiber to a heat treatment whereby the glass fiber is relatively slowly pulled through a controlled heat zone having a temperature gradient extending from a temperature at or at least relatively close to the softening temperature of the glass fiber to about room temperature.
