【摘要】 随着碳纳米管增强铝基复合材料制备工艺的不断完善，碳纳米管的难分散问题被妥善解决，复合材料的强度有所提高，但复合材料的高模量、高强度没有得到充分利用，并出现“强度–塑性”倒置现象。本文总结了近年来对碳/铝复合材料界面结构、晶粒结构与复合构型设计的调控手段，讨论了界面结构强度对碳纳米管载荷传递效率的影响，分析了出现倒置现象的原因，并针对复合材料塑韧性差的问题，提出了调控思路，为制备强度高、韧性强的碳纳米管增强铝基复合材料提供依据。更多还原

【Abstract】 With the continuous improvement on the preparation process of the carbon nanotube-reinforced aluminum matrix composites, the difficult dispersion problem of the carbon nanotubes has been properly solved, and the composite strength has been improved, but the high modulus and high strength of the composites have not been fully utilized, and the “strength-plastic” inversion phenomenon has appeared. The adjustment methods of interface structure, grain structure, and composite configuration design of the carbon/aluminum composites in recent years were summarized in this paper, the influence of interface structure strength on the load transfer efficiency of the carbon nanotubes was discussed, the causes of inversion phenomenon were analyzed, and the control ideas were proposed to solve the problem of poor plastic toughness of the composites, providing the basis for preparing the carbon nanotubereinforced aluminum matrix composites with high strength and toughness.更多还原
