碳纳米管增强铜基复合材料的类注射成型方法制备研究
Powder Injection Moulding-like for Carbon Nanotubes ReinforcedCopper Matrix Composite
摘要
Abstract
A powder injection moulding-like process for producing carbon nanotubes reinforced copper matrix composites was developed .The process is a promising low-cost and large scale technique for produc-tion of complex copper metal matrix nanometer composite .The result reveals that uniform dispersion of carbon nanotubes in copper matrix can be achieved by using polymer-based binder .It is found that debind-ing ,sintering ,hot rolling temperature and content of carbon nanotubes have significant effect on the micro -structure and properties of composites .The composite with 1 w .t％ carbon nanotubes exhibited the best mechanical performance .Furthermore ,hot rolling approach plays important role not only for work-harden-ing effect ,but also for uniform distribution of carbon nanotubes in matrix ,resulting in significant improve-ment in density and hardness for composite .关键词
