Abstract
The invention provides a multi-layer metamaterial and a preparation method of the multi-layer metamaterial. Honeycomb structure strengthening materials are adhered to the surface of each metamaterial function layer, so that the manufactured multi-layer metamaterial is good in mechanical property, and cannot be easily bent, the whole multi-layer metamaterial is light in weight, and therefore application of the multi-layer metamaterial is expanded.
Description
[technical field]
The present invention relates to super material field, relate in particular to super material of a kind of multilayer and preparation method thereof.
[background technology]
Super material refers to artificial composite structure or the composite material that some have the not available extraordinary physical property of natural material.Structurally ordered design by on the key physical yardstick of material can break through the restriction of some apparent natural law, thereby maybe must exceed the meta-materials function of the intrinsic common character of nature.The character of super material and function mainly come from its inner structure but not constitute their material, therefore are design and synthetic super material, and people have carried out a lot of research work.2000, people such as the Smith of University of California pointed out that the composite construction of the metal wire of periodic arrangement and open loop resonator (SRR) can realize that DIELECTRIC CONSTANT and magnetic permeability μ simultaneously for negative two negative material, also claim left-handed materials.They are again by making the two negative material that metal wire and SRR composite construction have been realized two dimension at printed circuit board (PCB) (PCB) afterwards.And the mechanical performance of the super material of the multilayer of preparation is not strong at present, easily bending.
[summary of the invention]
Technical problem to be solved by this invention is: super material of multilayer of a kind of satisfactory mechanical property and preparation method thereof is provided.
The present invention solves the problems of the technologies described above the technical scheme that adopts: the super material of a kind of multilayer, comprise a plurality of super material function layers, and the surface of each described super material function layer is stained with reinforcing material.
Described reinforcing material is the honeycomb reinforcing material.
Described honeycomb reinforcing material is made by nonmetal.
Each described super material function layer comprises the micro-structural that substrate and array are periodically arranged on substrate.
Described micro-structural is the derived structure of I-shape construction or I-shape construction.
Described micro-structural is made by copper cash or silver-colored line; Described substrate is ceramic substrate, ptfe substrate, polyphenylene oxide substrate or epoxy glass fiber fabric base plate.
A kind of method for preparing the super material of multilayer, described method may further comprise the steps:
A, the super material function layer that will prepare are fixed on the reinforcing material by binding agent;
B, another reinforcing material sticked to the surface of super material function layer by binding agent;
C, repeating step a and b form layer structure;
D, curing obtain the super material of multilayer.
Described reinforcing material is the honeycomb reinforcing material.
Described honeycomb reinforcing material is made by nonmetal.
Each described super material function layer comprises the micro-structural that substrate and array are periodically arranged on substrate.
Wherein the honeycomb reinforcing material is a kind of sandwich, be to glued joint the high-strength light sheet material that forms by up and down two-layer thin plate and middle hexagon honeycomb core with adhesive, wherein in the middle of the hexagon honeycomb core also can be polygon honeycomb core such as three limits, four limits.Its interlayer honeycomb core structures and surface material can adopt multiple unlike material to make, to satisfy different technical performance requirements.It is human a kind of structural material of saving material, strength-weight ratio maximum most known to up to now, its characteristics mainly contain materials province, specific strength height, specific stiffness height, structural stability good, can predict uniform buffer intensity, fatigue resistance is good and heat-insulation and heat-preservation etc.
Beneficial effect of the present invention is: the surface of each super material function layer is stained with the honeycomb reinforcing material, and the satisfactory mechanical property of the feasible super material of making of multilayer is difficult for bending, and the super material light weight of whole multilayer, thus the application of having expanded super material.

C, repeating step a and b form layer structure;
D, curing obtain the super material of multilayer.
Wherein the honeycomb reinforcing material is a kind of sandwich, be by two-layer thin plate and middle hexagon honeycomb core are gluedd joint the high-strength light sheet material that forms with adhesive up and down, middle hexagon honeycomb core also can be polygon honeycomb core such as three limits, four limits, and what select for use in the present embodiment is the hexagon honeycomb core.Its interlayer honeycomb core structures and surface material can adopt multiple unlike material to make, to satisfy different technical performance requirements.It is human a kind of structural material of saving material, strength-weight ratio maximum most known to up to now, its characteristics mainly contain materials province, specific strength height, specific stiffness height, structural stability good, can predict uniform buffer intensity, fatigue resistance is good and heat-insulation and heat-preservation etc.
The super material of this multilayer, as shown in Figure 3, what make is four layers of super material, also can make the super material of the required number of plies according to actual needs, comprise a plurality of super material function layers, the surface of each super material function layer 2 is stained with reinforcing material, and described reinforcing material is by metal honeycomb reinforcing material 1.
Each super material function layer comprises the micro-structural that substrate and array are periodically arranged on substrate, micro-structural is the derived structure by copper cash or silver-colored thread I-shape construction or I-shape construction; Described substrate is ceramic substrate, ptfe substrate, polyphenylene oxide substrate, epoxy glass fiber fabric base plate or other special composite base plate.
The satisfactory mechanical property of the super material of this multilayer is difficult for bending, and the super material light weight of whole multilayer, thus the application of having expanded super material.
