Rapid Deposition of Al2O3/SiO2 Composite Coating on Carbon Fiber Fabric

In the paper, a uniform and continuous Al2O3/SiO2 composite coating was prepared on each fiber of carbon fiber fabric via room-temperature aqueous plasma electrolysis technique. The micromorphology and anti-oxidation property of the Al2O3/SiO2-coated carbon fiber fabric were systematically investigated. The dense and continuous Al2O3/SiO2 composite coating was uniformly deposited on each fiber of carbon fiber fabric. The thickness of coating was 120–150 nm. The Al2O3/SiO2 composite coating could protect the carbon fiber fabric from oxidation above 1000 °C. In addition, it could be seen 300 m carbon fiber fabric were coated continuously by high-quality Al2O3/SiO2 composite coating.
