The influence of a polyimide nanocoating on the tensile properties of polyacrylonitrile-based high tensile strength (T1000GB) and pitch-based high modulus (K13D) carbon fibers was investigated. The pyromellitic dianhydride/4-4′-oxydianiline polyimide nanocoating was deposited by high-temperature vapor deposition polymerization. The polyimide nanocoating on a filament had a thickness of ∼100 nm. The tensile strengths and Weibull modulus of the uncoated and coated fiber bundle were measured using a polyimide-impregnated bundle-composite. The introduction of the polyimide nanocoating on carbon fibers improved the Weibull modulus of carbon fiber bundle. However, the polyimide nanocoating is more effective for the PAN-based carbon fibers.
