Description
Technical field
The invention belongs to textile field, it is related to a kind of frequency selection stereo fabric based on cut velvet and looped pile periodic structure.
Background technology
Periodic structure is formed according to the distance arrays of setting by specific cell configuration, and it is to different frequency electromagnetic wave
Albedo is absorbed different, so the feature with frequency selectivity transmission or reflection, can be regarded as a kind of space filter
Ripple device.Periodic structure is divided into plan periodic structure and D periodic structure, plan periodic structure in each electromagnetic band and
The numerous areas such as communication, antenna, radar have important application, and D periodic structure is mainly used in radome and inhales ripple material
Material.
Periodic structure based on textile.It is in tradition research to be limited to planar structure and simple metal material more, it is mostly derived from flat
Face periodic structure easily prepared, calculate simple, can be with MULTILAYER COMPOSITE and loading etc..Additionally, metallized textiles and tool
There is the process technology of the textile of metallic character increasingly mature, people is begun to focus on plan frequency selection textile
Exploitation, and certain progress has been obtained, such as Chinese patent application CN200910054882.9 utilizes the side of chemical silvering
Method forms one layer of silver on dacron surface, so as to assign fabric capability of electromagnetic shielding；Chinese patent application
CN200910048743.5 forms one layer of copper using the method for electroless copper on dacron surface, so as to assign fabric electricity
Magnetic shield performance；Chinese patent 200810204134.X is made fabric realization electricity using permalloy with yarns interwoven is taken
Magnetic screen；United States Patent (USP) US19970943957 the chemical-fibres filaments such as nylon are carried out it is silver-plated be made electrically conductive filament yarn, then
The anti-radiation knitted thing of high connductivity is made into using knitted structure；Chinese patent CN1130223 provide a kind of electric heating, shielding,
Anti-static multifunctional conductive fabric and preparation method thereof, conductive fabric low cost, light weight, the softness being made is washable,
Environmental stability and re-workability well can be used as conductive material, electromagnetic wave, micro-wave screening material and plane heating materials；It is beautiful
State patent US2014022139-A1 discloses a kind of electronic band gap characteristic frequency choosing for being configured with flexible electromagnetism textile
Select surface, to suppress edge and curved diffraction effect, the frequency-selective surfaces fabric have resistance designability, lightweight,
Flexibly the advantages of.As can be seen here, metallized textiles will be turned into advantages such as high flexibility, lightweight, facility, low costs
The good substitute of metal.
In the middle of periodic structure practical application, it is related to limited periodic structure or stereochemical structure, such as radome more, it is wearable
Formula electromagnetism clothes etc..Its border or multidimensional influence factor are more complicated, but at present to D periodic structure, especially base
In stereo fabric periodic structure also without systematic research and complete theory.From unlike plan periodic structure：
Plan periodic structure mainly realizes the absorption to electromagnetic wave using the effect of construction unit substrate absorbing material, and the cycle ties
Structure unit provides frequency selection index system to the electromagnetic wave for passing through.D periodic structure is mainly by architectural feature to electromagnetism
Ripple produces absorption, can avoid depending on unduly in planar structure the defect of absorbing material.Due to the multidimensional of hyperspace
Factor, D periodic structure can also obtain more spaces and flexibility in design.
