摘　　要：纤维增强SiC陶瓷基复合材料具有密度低、强度高、耐高温、抗氧化、耐腐蚀等优点,在航空航天及其他高温条件使用领域具有广泛的应用潜力。然而难加工特点制约了这类材料的广泛使用。由于存在硬度高、脆性大和各向异性特点,高精度低损伤加工成为其工程应用必须解决的关键技术之一。本文主要综述了近年来纤维增强SiC陶瓷基复合材料加工技术研究进展,综合分析了不同加工方法的加工原理、理论模型构建、工艺参数优化、表面质量控制与损伤形成机制等,讨论了当前存在的主要问题,对未来研究方向提出了发展与展望。Fiber reinforced SiC matrix composites(FRCMC-SiC)have significant potential in aerospace application and other high temperature conditions due to their special properties such as low density,high strength,thermostability,anti-oxidation and anti-ablation.However,the application of these composites has been hindered seriously because of their poor machining characteristics.The high-quality and low-damage machining technology must be solved in the use of this kind of high hardness,high brittleness and anisotropy materials.In this paper,the recent progress on the different machining technologies of FRCMC-SiC is reviewed.The material removal mechanism,theoretical model construction,parameters optimization,defect form and surface quality control are summarized and discussed.Finally,the existing problems are discussed,and the development trend of machining technology of FRCMC-SiC in the future is also put forward.
