Microstructure, mechanical and electrical properties of Al/carbon nanotubes composite: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

On this analysis, Al composites bolstered with carbon nanotubes (CNTs) have been fabricated by powder metallurgy. The produced samples have been ready from CNTs with 0, 0.5, 1, 1.5, 2, 2.5 and 5 wt.%. The milling course of was carried out by a planetary ball mill and the samples have been compacted below a power of 10 tons for 1 minute. Previous to measurements, the samples have been heated at 580 °C for half an hour. Additionally, electrical resistance, density and hardness of the samples have been measured and the impact of sintering temperature on the samples with 1.5 wt.% of CNTs was investigated. The samples have been heated at 480, 580, 700 and 1200 °C for half an hour and it was noticed that the annealing temperature had a major impact on the hardness enhance of the samples. It was discovered that the annealing time didn’t have a major impact on the hardness of the samples. Measurements confirmed that by rising the wt.% of CNTs, the and density of the composite repeatedly decreased however the electrical resistance and hardness of the samples elevated.
