Outline of Final Research Achievements

Carbon nanotube (CNT)-Al composite has attracted extensive attention due to the extraordinary mechanical, thermal and electrical properties of CNTs. Carbon nanotube (CNT)-Al composite has attracted extensive attention due to the extraordinary mechanical, thermal and electrical properties of CNTs. Unfortunately, the difficulty in achieving a uniform CNT dispersion and the imperfect interfacial bonding severely hinder its development. For strengthening the interface, it is reported that formation of Al4C3 is a good way for improving the load transfer. The results showed the tensile strengthen of CNT-Al composites really increased slightly after heat treatment. On the basis of the investigation on the thermal expansion behavior of CNT-Al composites, the effect of Al4C3 formation on the load transfer was discussed. It is found the coefficient of thermal expansion (CTE) of the composites decreased with increasing CNT concentrations due to the constraining effect of CNTs.
