Abstract

Using TTIP as a starting material, we investigated sol-gel fabrication of TiO₂-coated carbon fibers, and optimized the following fabrication parameters: coating solution composition, pulling rate and dipping time. TG measurement results indicated that no weight reduction occurred in the coated fibers air up to at a high temperature of 1000°C. From these experiments, it was concluded that the fabricated carbon fibers coated with TiO₂ were oxidation resistant.
