采用泥浆法将碳化硅颗粒混杂到碳化硅束丝纤维中，然后用液相压渗工艺制备出连续碳化硅纤维与颗粒共同增强的铝基复合材料。通过光学金相和扫描电镜的分析及力学性能测试发现：碳化硅颗粒混杂于纤维中，可以避免纤维的相互接触，从而有利于铝液的完全浸渗。颗粒的混杂还可以较明显地改善ＳｉＣ＿ｆ／Ａｌ复合材料的弹性模量，对强度影响不大。液相压渗过程中，界面反应及纤维的破断是造成复合材料强度较低的主要原因。
The silicon carbide particles were mixed into the SiC fiber by mud method. Then the aluminum matrix composites reinforced by continuous silicon carbide fibers and particles were prepared by liquid-phase infiltration process. By optical metallography and scanning electron microscopy analysis and mechanical properties test found that: silicon carbide particles mixed in the fiber, fiber can avoid contact with each other, which is conducive to the complete impregnation of aluminum liquid. The mixture of particles can also significantly improve the elastic modulus of SiC_f / Al composites, with little effect on the strength. In the process of liquid phase pressure infiltration, the interfacial reaction and fiber breakage are the main reasons for the lower strength of composite materials.
