Preparation method of high-strength corrosion-resistant lining of carrier-based aircraft fuel pipeline
The invention discloses a preparation method of a high-strength corrosion-resistant lining of a carrier-based aircraft fuel pipeline, which comprises the following steps: winding carbon fiber cloth on a graphite rod to obtain a carbon fiber cloth preform; depositing a pyrolytic carbon interface phase on the carbon fiber cloth preform by adopting a CVI (Chemical Vapor Infiltration) process to obtain a carbon fiber cloth preform deposited with the pyrolytic carbon interface phase, and then drawing out the graphite rod; depositing a silicon carbide matrix on the carbon fiber cloth preform deposited with the pyrolytic carbon interface phase by adopting a CVI (Chemical Vapor Infiltration) process to obtain a carbon fiber reinforced silicon carbide ceramic matrix composite material; silicon carbide coatings are deposited on the inner surface and the outer surface of the carbon fiber reinforced silicon carbide ceramic-based composite material by adopting a CVD (Chemical Vapor Deposition) process to obtain the carbon fiber reinforced silicon carbide ceramic-based composite material deposited with the silicon carbide coatings, and the carbon fiber reinforced silicon carbide ceramic-based composite material is used as the lining of the carrier-based aircraft fuel pipeline. The prepared composite material lining has the excellent performance of high strength, high temperature resistance, corrosion resistance, wear resistance and the like.
