Description

Technical Field

[0001] This utility model relates to the field of composite material development technology, specifically a functional zone composite material. Background Technology

[0002] With the rapid development of my country's industry, many new composite materials have emerged. Composite materials are materials that combine metals with metals or metals with non-metals. Combining different materials can compensate for the defects of a single material.

[0003] Currently, my country offers a wide variety of composite materials. Especially given resource shortages, the recycling and composite utilization of waste materials has begun to emerge. This phenomenon has certain material and energy-saving effects. However, there are still some shortcomings in terms of both the functionality of the composite materials themselves and market demand. For example, existing copper-steel composite conductive busbars utilizing the skin effect use copper for the outer layer to achieve conductivity and steel for the inner layer to achieve structural load-bearing. Replacing copper with steel reduces costs without affecting conductivity, which has some effect. However, steel is also a relatively expensive metal. If cheaper fly ash or waste residue were used to completely or partially replace the copper-steel composite busbars, fulfilling the functions of conductivity, load-bearing, and filling respectively, the cost would be even lower, and waste utilization would be achieved, resulting in better economic benefits.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] See Figure 1 A functional composite material, comprising an outer metal layer 1 and an inner core disposed inside the outer metal layer 1; the outer metal layer 1 and the inner core, and the different functional areas within the inner core, are compacted and embedded connections, wherein the outer metal layer 1 is mainly made of metal and has a closed structure with cavities, and at least one functional area is disposed within the outer metal layer 1 to form the composite material of this embodiment.

[0025] In some embodiments, the outer metal layer 1 of this composite material mainly uses a structural material with strong plastic deformation capacity, such as silver, copper, superconducting copper alloy, or stainless steel. When copper or silver is used for the outer metal layer 1, the skin effect of the current is utilized to improve the conductivity and electrical properties of the outer metal layer 1; when stainless steel is used for the outer metal layer 1, the corrosion resistance of stainless steel is utilized to improve the service life of the overall product.

[0026] In some embodiments, the number of inner cores of this composite material can be set according to performance requirements, for example, 1-10 functional areas. The composite material of this embodiment includes a second functional area 3 and a third functional area 4. Each functional area uses different materials to combine to achieve different performance requirements, while also forming complementary characteristics with the outer metal layer 1 to improve the overall performance of the composite material product.

[0027] In some embodiments, specifically, the outer metal layer 1 is a ferrous or non-ferrous metal. The outer metal layer can utilize the skin effect to further ensure conductivity. Non-metallic fillers are densely filled within the outer metal layer. Compared to the solid inner core made entirely of precious metals in the prior art, this method can significantly reduce core weight and production costs while ensuring a certain conductivity through the skin effect. At the same time, the non-metallic fillers have good structural properties, which can further improve the structural strength of the product and prevent conductor instability.

[0028] For example, the functional areas of the inner core are made of low-carbon steel and slag powder.

[0029] For example, the functional areas of the inner core are made of copper tubes and fly ash.

[0030] It is worth noting that the above-mentioned composite material combinations are not limited to the embodiments listed above, and can be combined in other ways according to actual production needs.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
