| Description: |
Composite materials on based powder systems "copper – carbon nanotubes" with different carbon nanotubes contents ranging from 0 to 0,1 wt. % were prepared by a electrocontact sintering. Its has shown that this composites have anisotropic thermal and electrical conductivity. It has been found that during uniaxial molding, in the process of electrocontact sintering, carbon nanotubes are oriented in one direction, which leads to a change in the values of the studied characteristics in this direction. Dependences of the change in the thermal conductivity, the electrical resistance and the specific electrical conductivity of the composites on the content of the nanostructured filler are established. |
