摘　　要：采用SEM观察了预处理前后的碳纤维以及碳纤维预制件的形貌。结果表明 :预处理使碳纤维长径比满足制备合格预制件的要求 ,并有利于纤维在预制件中的均匀分散及预制件的成型 ;本工艺制备出的预制件纤维分布均匀 ,表面无团聚 ,碳纤维无氧化 ,可用于液态模锻法制备碳短纤维增强金属基复合材料。The appearance of carbon fiber before-and-after pretreatment and carbon fiber preforms were observered by scanning electron microscope。The results showed that the ratio between the length and diameter of the pretreated carbon fiber could fabricate qualified preforms。Therefore,it was beneficial to the well-distributed of fiber and the formation of preforms。The fiber in the carbon fiber preforms made by this processing was well dispersed and no gathering。And there was no carbon fiber oxidized in preforms。This made it possible for fabricating metal matrix composites with carbon short fiber with good properties by squeezing casting.
