| 摘 要： | 碳纤维经混杂SiCP后用压力浸渍成型方法制备成C/Al复合材料,分析混杂的SiCP对C/Al复合材料力学性能的影响。测试了制备成的复合材料性能,并用SEM对复合材料断面组织与断口形态进行分析。结果表明,混杂的SiCP可以分隔纤维,有利浸渍,使纤维分布均匀从而提高了复合材料的性能,而用sol-gel方法涂复SiC层并混杂SiCP可获得最佳的性能。

| Abstract: | The carbon fiber reinforced aluminium composite material was fabricated by means of vacuum pressure infiltration to study the effects on the infiltration and on the properties of the SiC particles hybridized in carbon fibers. The tensile and bending properties were determined and the microstructure and fractography were investigated by the SEM. It was demonstrated that the SiC_P hybridized in fibers can separate the clustered fibers and prevent the contact of fibers to provide a better fiber distribution ,which is beneficial to infiltration and composite material properties. Optimum properties have been shown in the material made up of sol-gel SiC coating fibers along with SiC_P hybridizing. |
