提出了一种制备碳纳米管增强铝基复合材料的方法。采用浸渍法将Co催化剂均匀地沉积在Al粉表面，然后采用化学气相沉积法在Al粉中生长碳纳米管，得到碳纳米管/Al复合粉体。将所得粉末进行短时间球磨后，通过压制、烧结和热挤压制备CNT/Al复合材料。在此过程中，良好分散的CNT增强体深深嵌入Al粉末中，与基体形成有效的界面结合。结果表明，添加2.5wt.%碳纳米管的抗拉强度为334 MPa，是未增强铝的1.7倍，且具有良好的延展性，断裂伸长率约为18%。因此，在CNT增强的Al复合材料中实现了良好平衡的强度和延展性。
An approach was developed to fabricate carbon nanotube (CNT)-reinforced Al composites. In a typical process, the Co catalyst was evenly deposited on the surface of Al powder by impregnation route, and then the CNTs were grown in the Al powder by chemical vapor deposition to obtain CNT/Al powders. After ball-milling of the obtained powders for a short time, the CNT/Al composites were fabricated by compacting, sintering and hot extrusion of the ball-milled powders. During this process, the well dispersed CNT reinforcement is deeply embedded in the Al powder forming an effective interface bonding with matrix. As a result, the CNT/Al composites containing 2.5wt.% CNTs exhibit the ultimate tensile strength of 334MPa which is 1.7 times higher than that of unreinforced Al, and good ductility of ∼18% elongation to failure. Thus, well-balanced strength and ductility are achieved in CNT-reinforced Al composites.
