Abstract:
By taking methane（CH4）as carbon source precursor gas and 3D needle-punched carbon fiber-prefabricated form as the deposition matrix, the effects of the deposition time, pressure and prefabricated form thickness in chemical vapor deposition （CVD） process on the thickness of pyrolytic carbon （PyC） interface layer were studied. Based on the study, the CVD technological parameters needed by preparing PyC interface layer with appropriate thickness on the surface of carbon fiber were optimized. Analysis on these effects reveals that, based on the existing furnace, with a deposition temperature of 1 000 ℃ and CH4 flow speed of 500 ml/min, deposition period 10 h and deposition at 5 kPa can produce the PyC interface layer with suitable thickness on the inner and outer surface of the fiber-prefabricated form with 5 mm thickness. If the thickness of carbon fiber- prefabricated form needs to be increased to 10 mm, the deposition period should be prolonged to 15 h while the
