Structure and properties of copper-based composite with different types of carbon nanostructures

The addition of various types of carbon nanostructures in copper matrix was studied. Fullerene soot, CNTs and rGO showed that the type of nanocarbon affects the distribution of the additive in the matrix and on the formation of the composite structure. A comparative analysis of the structure and properties for composite materials with various types of nanocarbon was carried out. Composites containing CNTs have the most uniform structure and showed a significant increase in hardness up to 190 HV, with a coefficient of friction equal to 0.22 and thermal conductivity was 75% of pure copper.
