▎ 摘　　要

NOVELTY - An aluminum-based composite material comprises 2-15 wt.% silicon, 0.01-0.5 wt.% lanthanum, 2.3-17.1 wt.% oxygen and 0.01-3 wt.% nano-carbon material, and remainder of aluminum. The nano-carbon material is modified graphene nano-flakes and/or modified carbon nanotubes. The modified carbon nanotubes are carbon nanotubes modified by gallic acid. The modified graphene nano-flakes are graphene nano-flakes modified by rutin. USE - Aluminum-based composite material (claimed). ADVANTAGE - The aluminum-based composite material has excellent mechanical property, hardness and tensile strength, and high density due to the presence of modified carbon nanotubes, and enhanced load transfer property, and can be prepared by simple and easy method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of aluminum-based composite material.
