Definitions
- the present invention relates to a composite material manufacturing apparatus, and more particularly, to a composite material manufacturing apparatus capable of continuously and uniformly dispersing a light weight dispersant in a relatively heavy specific dispersion medium.
- Copper and aluminum have been widely used as heat exchangers and heat sink materials since early, but the energy density is increased due to the high performance and high efficiency of the device. As a result, heat dissipation materials are required to be lighter, higher in strength and higher thermal conductivity.
- Aluminum which is a lightweight material, has been attracting attention as a heat dissipating material since early, but alloying is inevitable to obtain suitable mechanical properties as a heat dissipating structural material. Such alloying can improve the workability and mechanical properties of the aluminum material, but lowers the thermal conductivity and the electrical conductivity.
- the thermal and electrical properties of nanomaterials can be improved by complexing them with nanomaterials such as carbon nanotubes, which have superior thermal and electrical properties than aluminum.
- nanomaterials such as carbon nanotubes
- the powder metallurgy method has been widely used as a method of manufacturing such a composite material, and the powder metallurgy method has been applied to the complexation of carbon nanotubes, and has shown some results.
- the powder metallurgy method has a problem in economy and scale-up to cope with the increasing demand for composite materials, and attention is being paid to the complexation technology by the casting method.
- the problem of immersing the carbon nanotube dispersant in the aluminum molten metal as the dispersion medium should be solved first. It is smaller than this dispersion medium, so that immersion is difficult due to buoyancy.
- the present invention relates to the complexation of a material having a lighter dispersion than a dispersion medium, such as a carbon nanotube-aluminum composite material.
- carbon nanotubes are lighter in weight than aluminum and have low dispersibility. Therefore, they are not easily mixed in the molten aluminum. Therefore, the powder metallurgy method or the technique of laminating carbon nanotubes on aluminum foil is applied to the aluminum carbon nanotube composite material. There is a problem that is difficult to mass-produce.

It is mixed with the carbon nanotubes supplied through the two injection pipe (14).
- the inner surface of the aluminum molten metal naturally rises due to the buoyancy action of the carbon nanotubes and is fixed to the solidification surface formed at the intermediate position of the cooling unit 50 as opposed to the conventional gravity system. .
