Problems solved by technology

However, the sintering temperature is as high as 800-1000°C, and the holding time is as long as 3-4 hours. This sintering temperature and holding time will lead to a significant loss of strength of the basalt fiber during the sintering process, which is not conducive to the improvement of the strength of the copper-based composite material.

Abstract

The invention discloses a preparation method of a copper-plated basalt fiber reinforced copper-based composite material, which comprises the following steps: S1, carrying out preheating treatment on basalt fibers, and then carrying out roughening treatment by adopting hydrofluoric acid; s2, the basalt fibers subjected to roughening treatment are placed in a copper plating solution to be subjected to chemical copper plating treatment; and S3, the basalt fibers subjected to copper plating and copper powder are mixed and then subjected to compression molding, the copper-plated basalt fiber reinforced copper-based composite material is prepared through spark plasma sintering, and the content of the copper-plated basalt fibers in the copper-based composite material is 1%-3% by weight. The invention further provides the copper-plated basalt fiber reinforced copper-based composite material prepared through the method and application of the copper-plated basalt fiber reinforced copper-based composite material. According to the preparation method of the copper-plated basalt fiber reinforced copper-based composite material, a copper-plated layer is formed on the surface of the basalt fiber through a chemical copper plating method, so that the interface bonding between the basalt fiber and copper is improved, and the mechanical property of the copper-based composite material is improved.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a copper-plated basalt fiber-reinforced copper-based composite material and a preparation method and application thereof. Background technique [0002] Copper has excellent electrical and thermal conductivity and processing properties, and has been widely used in aerospace, marine engineering, electronics and automobiles. However, the strength of pure copper is relatively low, which has greatly limited the application of copper in some fields. The introduction of a second phase with higher strength, such as particles, whiskers, fibers, etc., into the copper matrix, thereby preparing a copper matrix composite material, not only improves the strength of the copper material, but also makes the advantages of each component fully exerted. Therefore, received extensive attention and research. [0003] As a new type of environmental protection material, basalt f...
