Two-dimensional T300 carbon fiber-reinforced aluminum alloy matrix (2D CF/Al) composites were prepared by the liquid extrusion infiltration (LEI) process with the matrices of 6061Al and ZL102 alloys. Scanning electron microscopy (SEM) detected a satisfactory infiltration effect for both composites. The fiber distribution was uniform, and casting microdefects were not revealed. Transmission electron microscopy (TEM) analysis disclosed the matrix-carbon fibers interface reaction, the brittle Al₄C₃ phase. Al₄C₃ sizes were found to be about 150 and 400 nm in 2D CF/6061Al and 2D CF/ZL102 composites, respectively, the interface reaction of a ZL102 matrix was more pronounced. As compared to pure cast alloys, the ultimate tensile strength increased by 134.5. SEM analysis of the tensile specimen fracture demonstrated that the fracture of a 2D CF/6061Al composite was reasonable and for a 2D CF/ZL102 composite it was via the brittle mode, these were caused by the interface bonding.

通过液相挤压浸渗（LEI）工艺，以6061Al和ZL102合金为基体，制备了二维T300碳纤维增强铝合金基体（2D CF / Al）复合材料。扫描电子显微镜（SEM）检测到两种复合材料均具有令人满意的渗透效果。纤维分布均匀，并且没有发现铸造的微缺陷。透射电子显微镜（TEM）分析揭示了基体-碳纤维的界面反应，即脆性的Al ₄ C ₃相。铝₄ C ₃发现在2D CF / 6061A1和2D CF / ZL102复合材料中，粒径分别约为150和400 nm，ZL102基质的界面反应更加明显。与纯铸造合金相比，极限抗拉强度提高了134.5。拉伸试样断裂的SEM分析表明，2D CF / 6061Al复合材料的断裂是合理的，而对于2D CF / ZL102复合材料，断裂是通过脆性模式造成的，这是由于界面粘结引起的。
