以高纯铝粉和多壁碳纳米管（MWCNTs）为原料，采用球磨、冷压、真空烧结、热挤压等工艺制备了MWCNTs/Al复合材料。结果表明，当烧结温度为863 K，烧结时间为4 h时，MWCNTs/Al复合材料具有较好的综合性能，其抗拉强度和伸长率分别达到156 MPa和21%。当烧结时间为4 h时，随着烧结温度的升高，复合材料的综合力学性能逐渐提高。当烧结温度提高到923 K时，复合材料的抗拉强度达到167 MPa，是退火态高纯铝的3倍以上，这主要是由于烧结温度的提高使复合材料的致密度提高，界面结合更好。碳纳米管的拔出现象在断口处较为明显，载荷传递可能是其主要的强化机制。
By using high purity aluminum powders and multi-walled carbon nanotubes (MWCNTs) as raw materials, MWCNTs/Al composites were fabricated with ball milling, followed by cold pressing, vacuum sintering, and hot extrusion. It was found that when the sintering temperature was 863 K, MWCNTs/Al composite sintered for 4 h showed good comprehensive properties, and its tensile strength and elongation reached to 156 MPa and 21%, respectively. The comprehensive mechanical properties of the composites became better with raising sintering temperature when the sintering time was 4 h. When the sintering temperature raised to 923 K, the tensile strength of the composite reached to 167 MPa which is three times more than that of annealed high purity aluminum, mainly due to the higher density and better interface bonding resulted from higher sintering temperature. CNTs’ pulling out were observed obviously in the fractured surfaces, and load transfer may be the main strengthening mechanism.
