Abstract

The invention provides a composite material which comprises a supporting layer and a surface layer, wherein the surface layer is arranged on the supporting layer; the supporting layer is prepared through soaking a first material in a resin combination and then curing the obtained product, the first material has fiber properties, the surface layer is composed of a second material, and the second material has metal properties; the linear thermal expansion coefficient of the resin combination is close to the linear thermal expansion coefficient of the second material; and the first material is a high-strength and high-hardness material. Compared with the prior art, the composite material provided by the invention is high in strength and hardness, and the surface of the composite material has a richer appearance effect. The invention also provides a preparation method of the composite material and an electronic device with the composite material.

Description

technical field

[0001] The invention relates to the technical field of material synthesis, in particular to a composite material and a preparation method thereof. Background technique

[0002] Carbon fiber is a microcrystalline graphite material obtained by carbonization and graphitization of organic fibers. It not only has the inherent characteristics of carbon materials, but also has the flexibility and processability of textile fibers. It is a new generation of reinforcing fibers. Compared to conventional glass fibers (GF), the Young's modulus of carbon fibers is more than 3 times higher. Compared with Kevlar fiber (KF-49), carbon fiber not only has about twice the Young's modulus, but also does not swell or swell in organic solvents, acids and alkalis, and is corrosion-resistant. It is precisely because of the many advantages of carbon fiber that it is widely used in automobiles, electronics, textiles, military industry, sports equipment and other fields.
