Problems solved by technology

[0002] At present, the folding parts of electronic products on the market mainly use the rotating shaft to realize the folding function. The structural design of the existing rotating shaft occupies a relatively large space, which hinders the design requirements of the existing thin and light electronic products. In addition, the folding times of the rotating shaft itself also exist. Limitation, which affects the service life of electronic products

Embodiment Construction

[0027] The present invention is described below in conjunction with specific embodiment:

[0028] Such as figure 1 As shown, a composite material includes a flexible base layer 2 and metal layers 1 arranged on both sides of the flexible base layer 2, the thickness of the flexible base layer 2 is 0.01-0.03mm, and the thickness of the metal layer 1 It is 0.05-0.08mm.

[0029] Further, the flexible base layer 2 and the metal layer 1 are integrally formed through a bonding stamping process or a hot-melt process.

[0030] Further, the flexible base layer 2 is a silicone layer.

[0031] Further, the metal layer 1 is an aluminum layer or a copper layer or a stainless steel layer.

[0032] When the metal layer is a stainless steel layer, the composition of the stainless steel is as follows:

[0033] Element mass percentage nickel 1.2～5.0 chromium 12～20 manganese 9～17 silicon ≤0.5 carbon ≤0.20 nitrogen ≤0.20 phosphorus ≤0.045 ...

Abstract

The invention discloses a composite material and a preparation method thereof. The composite material is characterized by comprising a flexible substrate layer (2) and metallic layers (1), wherein themetallic layers (1) are arranged on both sides of the flexible substrate layer (2); the thickness of the flexible substrate layer (2) is 0.01-0.03mm; and the thicknesses of the metallic layers (1) are 0.05-0.08mm. Compared with the prior art, the spatial ratio of a rotating shaft in the prior art can be saved by using an integral molding technique of a three-layer structure, and in addition, by virtue of the strength of metals and the toughness of silica gel, the composite material has the fatigue strength of 10000 times or longer, and folding requirements of electronic products can be met.

Description

technical field [0001] The invention relates to a composite material, in particular to a foldable composite material. Background technique [0002] At present, the folding parts of electronic products on the market mainly use the rotating shaft to realize the folding function. The structural design of the existing rotating shaft occupies a relatively large space, which hinders the design requirements of the existing thin and light electronic products. In addition, the folding times of the rotating shaft itself also exist. Limitations affect the service life of electronic products. Contents of the invention [0003] In order to solve the defects of the above-mentioned technologies, the present invention aims to provide a composite material and its preparation method and electronic products using it. The folding device made of the composite material occupies a small space, and the effective folding times can reach more than 10,000 times . [0004] Concrete invention conten...
