摘　　要：碳/碳化硅是近年来发展起来的一种新型高性能陶瓷基摩阻材料,具有密度低,抗氧化性好,摩擦性能高且性能稳定等一系列优点,在高速列车、飞机和重型汽车等高能载制动领域具有广泛的应用前景。反应性熔体浸渗法是制备碳/碳化硅摩阻复合材料的有效途径。从碳/碳化硅摩阻复合材料的设计出发,深入分析了反应性熔体渗透过程的热力学条件,Si-C反应体系的基本特征以及动力学规律。针对短纤维模压和三维针刺等两种典型C/SiC复合材料的制备过程,对材料的微结构特征和摩擦磨损性能进行了系统论述。同时,对红外热成像、X射线透射和工业CT等先进工程检测方法在碳/碳化硅摩阻复合材料构件上的应用进行了分析。Carbon/silicon carbide composites （C/SiC） are a new type of high performance ceramic matrix friction material developed in recent years. C/SiC composites possess a series of outstanding advantages such as low density, good oxidation resistance and a high and stable coefficient of friction. It has found a wide range of applications in the field of high energy braking for high speed trains, aircraft and heavy vehicles. The design of C/SiC friction composites, the thermodynamic conditions of the reaction mect infiltration infiltration process are analysized. The basic characteristics and kinetic characteristics and friction and wear performances of typical short-fiber pressed and three-dimensional needled C/SiC composites are deccribed. The application of advanced engineering detection technology such as infrared thermography, X-ray transmission and industrial computerized tomography in C/SiC friction composite component parts was also discussed.
