1 Production methods of CNT-reinforced Al matrix composites: a review https://jourcc.com/index.php/jourcc/article/view/jcc211 10.29252/jcc.2.1.1 20.1001.1.26765837.2020.2.2.1.9 1 Carbon nanotubes (CNTs)-reinforced aluminum composites have attracted attention due to their high specific strength low density, which makes them suitable for the use in aerospace and automobile industries. In this review, preparation methods of Al/CNTs composites for achieving a homogeneous desperation of the CNT in the Al matrix are summarized. In addition, the effect of processing methods on carbon nanotube distribution and enhancement of mechanical properties such as toughness, wear behavior and hardness of the nanocomposites are reviewed. Improvement of mechanical characteristics was observed by the incorporation of carbon nanotubes in aluminum matrix. The strengthening factors gained by the carbon nanotubes addition are the interface of metal and CNTs and the chemical and structural stability of CNTs. 1 9 Iman Tajzad Majlesi Branch, Islamic Azad University (IAU) Iran i_tajzad@yahoo.com Ehsan Ghasali Materials and Energy Research Center Iran info@jourcc.com Metal Matrix Composites Nanocomposite Spark Plasma Sintering Powder Metallurgy Mechanical Properties Article1.pdf [1] V.S.
