The Mechanical Property of Multi-walled Carbon Nanotube reinforced 1060 Aluminum Composites by Friction Stir Processing

Multi-walled carbon nanotubes(MWCNTs) reinforced 1060 aluminum matrix composites were prepared by friction stir processing (FSP). Morphologies of fracture,tensile strength,elongation and wear property were analyzed respectively. The results show that the distribution of macroscopic fracture appears a wide range of fiber morphology which presents microporous aggregation fracture. With increasing of the volume fraction of MWCNTs,the tensile strength and wear property of the composites increased while the elongation of composites decreased. Wear process of composites belongs to abrasive wear and shedding of solid lubricant film.
