中文摘要：

金属基复合材料中加入增强相,可以提高金属基体的力学性能和物理性能。碳纳米管和氧化铝颗粒作为常用的增强相,将二者同时加入金属基复合材料中,由于增强相之间的协同作用,可进一步提高其力学性能。加入0.8%（质量分数,下同）氧化铝颗粒、0.8%碳纳米管后,铜基复合材料的维氏硬度较之单独加入0.8%碳纳米管提高了5.4%;抗拉强度与单独加入0.8%碳纳米管和单独加入0.8%氧化铝颗粒相比分别提高了18.1%、41.6%;延伸率也分别提高了0.62倍、3.22倍。

英文摘要：

Reinforced phase can improve the mechanical properties and physical properties of metal matrix.The synergy between the reinforced phase,carbon nanotubes（ CNTs） and alumina（ Al2O3） particles as common reinforced phases,can further improve its mechanical properties.The Vickers hardness of copper matrix composites with 0.8 % Al2O3and0.8 % CNTs additions increase by 5.4% compared with that adding 0.8 % of CNTs only; Tensile strength increase by18.1% and 41.6% compared with that adding 0.8% CNTs and 0.8 % Al2O3respectively; Elongation increase by0.62 and 3.22 times compared with that adding 0.8 % CNTs and 0.8 % Al2O3 respectively.
