Method for improving oxidation resistance of carbon fiber reinforced silicon carbide ceramic-based composite material
The invention provides a method for improving the oxidation resistance of a carbon fiber reinforced silicon carbide ceramic-based composite material, and belongs to the technical field of composite materials. According to the preparation method, the SiC coating is deposited on the surface of the carbon fiber reinforced silicon carbide ceramic-based composite matrix material, and then pre-oxidation treatment is performed, so that the SiC coating on the surface of the carbon fiber reinforced silicon carbide ceramic-based composite matrix material generates a SiO2 film in situ, and the oxidation resistance of the carbon fiber reinforced silicon carbide ceramic-based composite material at 1200 DEG C or below is realized; meanwhile, the method has no influence on other properties of the carbon fiber reinforced silicon carbide ceramic matrix composite.
本发明提出了一种提高碳纤维增强碳化硅陶瓷基复合材料抗氧化性能的方法，属于复合材料技术领域。本发明通过在碳纤维增强碳化硅陶瓷基复合基体材料表面沉积SiC涂层，之后经过预氧化处理，使碳纤维增强碳化硅陶瓷基复合基体材料表面的SiC涂层原位生成SiO2膜，实现碳纤维增强碳化硅陶瓷基复合材料在1200℃及以下的抗氧化性能，同时此方法对碳纤维增强碳化硅陶瓷基复合材料本身的其他性能不产生影响。
