| Abstract: | Carbon fiber reinforced aluminium matrix (C / Al) composites have potential of high properties and wide application. And liquid infiltration is the most effective and economical fabrication processing for them. However, the improvement and stability of properties have been restricted because of interface reaction and non-wettability between carbon fiber and liquid aluminimu, which is the cause of fabrication complication and high cost. This paper presents a solution. The highest tensile strength of samples is up to 908MPa, which is achieved by fiber coatings and optimizing the liquid infiltration processing. Through the study of the influence of parameters of liquid-infiltration on the infiltration processing, material microstructure and properties, it is found that the pressure of liquid-infiltration is on guarantee, and the preheating temperature of fiber is the key to infiltration processing; the optimum parameters of the infiltration processing of C(SiC) / Al composites are given experimentally. |
