Description

Technical Field

[0002] Carbon fiber is a new type of high-strength and high-modulus fiber material with a carbon content of more than 90%. It has the characteristics of light weight, high strength, high modulus, high temperature resistance, corrosion resistance, and good conductivity. It is widely used in aerospace, automobiles, sports goods, construction and other fields. Copper foil is a very thin copper material, usually with a thickness of several microns to tens of microns. It has good electrical conductivity and thermal conductivity and is widely used in the electronics industry. Carbon fiber copper foil composite board is a new type of advanced composite material made of carbon fiber and copper foil through a specific process. Its structure mainly includes a carbon fiber layer and a copper foil layer. The two are closely combined through a specific composite process. The carbon fiber provides the strength and rigidity of the material, while the copper foil has excellent electrical conductivity and electromagnetic shielding effect. This composite material combines the respective advantages of carbon fiber and copper foil, and has the characteristics of high strength, high conductivity, corrosion resistance and wear resistance. When manufacturing carbon fiber copper foil composite boards, in order to provide a high temperature environment and make the carbon fiber and copper foil closely combined, hot pressing manufacturing equipment is usually used. Hot pressing manufacturing equipment is a device used to manufacture composite materials, which solidifies and shapes the material under high temperature and high pressure environment. The carbon fiber copper foil composite material board manufactured by hot pressing has higher strength, better electrical and thermal conductivity and fewer defects, and can be used in application scenarios with high performance requirements.

[0003] In the prior art, when hot pressing a carbon fiber copper foil composite material plate, in order to ensure the temperature and pressure inside the equipment, the equipment is usually sealed by a can cover.

At the same time, since the sealing of the connection between the can cover and the equipment cannot be well guaranteed, after long-term use, the connection between the can cover and the equipment may be loose, which can easily lead to heat loss and energy consumption. Therefore, in order to solve the above problems, a carbon fiber copper foil composite material plate and a hot pressing manufacturing equipment thereof are proposed. Summary of the invention
