▎ 摘　　要

NOVELTY - The precursor wire has a transition layer that is coated on the surface of the boron fibers, and a copper metal layer coated on the surface of the transition layer. The transition layer is a three-dimensional graphene hybrid B4C composite transition layer. The diameter of the boron fiber is 100-110 ~mm. The thickness of the three-dimensional graphene hybrid B4C composite transition layer is 1-2 ~mm, The three-dimensional graphene hybrid B4C composite transition layer includes amorphous B4C and three-dimensional graphene dispersed in the amorphous B4C, and the three-dimensional graphene forms a network structure in the amorphous B4C. USE - Boron fiber reinforced copper-based precursor wire for use in nuclear fusion reactor for providing clean energy source (claimed). ADVANTAGE - The continuous boron fiber-reinforced copper-based composite material with high tensile strength and high thermal conductivity is prepared by using the boron fiber-reinforced copper-based precursor wire. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing a boron fiber reinforced copper-based precursor wire; and (2) a continuous boron fiber-reinforced copper-based composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the prepares boron monofluoride or boron carbide or copper matrix composite material. (Drawing includes non-English language text)
