摘　　要：利用碳化硅颗粒在高温氧化气氛中表面生成一层致密的SiO_(2)薄膜,让SiO_(2)与水泥中的化合物发生水化物反应,生成类水产物C-S-H凝胶,既能对水泥强度做出贡献,又能使碳化硅颗粒锚定在水泥水化产物表面,并再次提升复合材料的力学性能。通过SEM显微镜,分析微观结构,解释复合材料的力学性能的提升原理。This paper,by using silicon carbide particles in the high temperature oxidation atmosphere generated on the surface of a dense layer of SiO_(2) thin film,let the SiO_(2) and cement compound of hydrate reaction,generating water product C-S-H gel,can not only contribute to the strength of cement,and can make the silicon carbide particles anchor on the surface of the cement hydration products,and improve the mechanical properties of composite materials again.Through SEM microscope,the microstructure was analyzed to explain the mechanism of improving the mechanical properties of composites.
