Abstract
A method for coating a carbon fiber for a composite structure may comprise applying a slurry onto a surface of the carbon fiber, wherein the slurry is a sol gel comprising a metal precursor and a carrier fluid, and heating the carbon fiber to a temperature sufficient to form a sol gel-derived layer on the carbon fiber. The slurry may comprise a metal precursor such as a metal salt or a metal alkoxide. The sol gel-derived layer may help prevent the carbon fiber from oxidizing.
