摘　　要：为满足结构件对高弹性模量镁基复合材料的需求,寻找理想的增强相和探索适合的复合工艺是镁基复合材料的发展趋势,向镁合金中添加碳纳米管(Carbon nanotubes,CNTs)增强相,具有强化细晶、应力转移、位错和热残余应力等作用,有利于改善镁合金强度和弹性模量等力学性能。从CNTs增强镁基复合材料制备工艺以及CNTs对复合材料弹性模量的影响等方面,详细地介绍了近年来CNTs增强镁基复合材料弹性模量的研究进展,并对未来研究方向提出若干建议。In order to meet the demand for structural parts with high elastic modulus of magnesium matrix composites, the key point is to find the ideal reinforcement and explore the suitable processing. The addition of carbon nanotubes（CNTs） in magnesium alloy can strength the fine-grained, stress transfer, dislocation and thermal residual stress, which is prefer to improve the tensile strength, elastic modulus and other mechanical properties of magnesium alloy. The research progress of magnesium matrix composite reinforced with CNTs was introduced based on the preparation technology of magnesium matrix composite by CNTs. The effects of CNTs on the elastic modulus of composite were specially focused. Furthermore, some research trends were also suggested.
