碳纳米管具有优异的力学性能和导电、导热性能，作为增强体引入铜基体中有望开发出新一代高强、结构功能一体化的复合材料。然而，碳纳米管在铜基体中的分散性较差及其与铜的润湿性问题，成为制备碳纳米管增强铜基(CNTs/Cu)复合材料的主要挑战，并显著影响了复合材料的性能。本文对目前有关制备碳纳米管增强铜基复合材料的主要方法包括碳纳米管前期预处理方法、碳纳米管在铜粉末中分散的方法、复合材料的烧结方法进行总结，概述复合材料的力学性能、摩擦磨损性能以及导电导热性能的研究进展，并提出思考和展望，以便为制备CNTs/Cu复合材料研究提供参考。
Research progress in carbon nanotube reinforced copper matrix composites prepared by powder metallurgy
Carbon nanotubes(CNTs)are considered as one of the ideal reinforcements for a new generation of high-strength,structurally and functionally integrated Cu matrix composites,due to their excellent mechanical properties as well as electrical and thermal conductivity.However,the poor dispersion ability and wettability of carbon nanotubes in the copper matrix pose significant challenges in preparation of CNT-reinforced copper-based(CNTs/Cu)composites,and these issues greatly affect the properties of the resulting materials.The main methods currently available for the preparation of carbon nanotubes reinforced copper-based composites were summarized,including the method of pretreatment of carbon nanotubes,the method of dispersion of carbon nanotubes in Cu powder,and the method of sintering of the composites.Besides this,the research progress on the mechanical properties,friction and wear performance,as well as electrical and thermal conductivity of the composites were presented.Some positive thinking and suggestions were made based on the current research status,which can provide reference for the preparation of CNTs/Cu composites.
