碳纤维增强铝基复合材料（C-f/Al）具有许多优异的性能，受到越来越多的关注。采用真空加压浸渗法制备了二维C-f/Al复合材料，该方法是一种集成技术，可提供高真空和高浸渗压力。通过显微组织观察，对比分析了比压对复合材料浸渗质量的影响。实验结果表明，在75 MPa的比压下，可以制备出质量较好的C-f/Al复合材料。结果表明，在比压为75 MPa时，C-f/Al复合材料的抗拉强度达到最大值，比基体合金提高了138.9%。
Carbon fiber reinforced aluminum matrix (C-f/Al) composite has many excellent properties, and it has received more and more attention. Two-dimensional (2D) C-f/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 C-f/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 C-f/Al composite reached maximum at the specific pressure of 75 MPa, which was improved by 138.9% compared with that of matrix alloy.
