▎ 摘　　要

NOVELTY - Metal-based composite material, preferably multilayer graphene/copper-aluminum-manganese shape memory alloy layered composite material comprises 1 wt.% copper-11.9 aluminum-2.5 manganese and copper51-zirconium14 inoculant, and 0.05-0.15 wt.% multilayer graphene, where the room temperature damping of the composite material is 0.044-0.0979, the tensile strength is 750.36-913.37 MPa, and the elongation after fracture is 8.34-13.48%. USE - The composite material is useful in the filed of vibration reduction and noise reduction. ADVANTAGE - The composite material has high damping degree and high strength. The method is simple, and has short production period. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the metal-based composite material.
