NOVELTY - Three-dimensional stacked body reinforced titanium-based composite material is claimed. The reinforcement of composite material is three-dimensional accumulation; three-dimensional stacked body is formed by stacking two-dimensional graphene, array of silicon oxide nanotubes grown on surface of two-dimensional graphene sheet, and one-dimensional titanium oxide nanowires aligned in outermost layer; matrix of composite material is titanium or titanium alloy, and mass ratio between reinforcement and matrix is 1:2-4. USE - Used as three-dimensional stacked body reinforced titanium-based composite material. ADVANTAGE - The reinforcement composite material: has high strength, excellent interface with matrix, excellent thermal stability, improved mechanical properties and low production cost; and overcomes problems of high preparation cost of titanium-based composite material, poor mechanical properties, and poor high temperature resistance in existing art.
