　　碳纤维增强铝基复合材料(Cf/Al)具有众多优良性能，因而受到广泛重视和应用。采用一体化成形且能够保证高真空度和高浸渗压力的真空吸渗挤压工艺制备二维碳纤维增强铝基复合材料(2D-Cf/Al)。通过微观组织观察，研究不同挤压力(比压)下复合材料的浸渗质量，得到最佳的比压值。结果表明：采用该工艺能够制备出浸渗质量良好的Cf/Al复合材料，最佳比压为75 MPa。此时，铝合金充填均匀，纤维损伤和铸造缺陷较少，浸渗情况良好，复合材料的力学性能最佳，其最大拉伸强度与基体合金相比提高138.9%。

Carbon fiber reinforced aluminum matrix (Cf/Al) composite has many excellent properties, and it has received more and more attention. Two-dimensional (2D) Cf/Al composites were fabricated by vacuum and pressure infiltration, which was an integrated technique and could provide high vacuum and high infiltration pressure. The effect of specific pressure on the infiltration quality of the obtained composites was comparatively evaluated through microstructure observation. The experimental results show that satisfied Cf/Al composites could be fabricated at the specific pressure of 75 MPa. In this case, the preform was infiltrated much more completely by aluminum alloy liquid, and the residual porosity was seldom found. It is found that the ultimate tensile strength of the obtained Cf/Al composite reached maximum at the specific pressure of 75 MPa, which was improved by 138.9% compared with that of matrix alloy.
