As preferably, described upper fiber cloth and lower fiber cloth adopt high-tenacity polyethylene fibre, Kafra fiber, poly-ester fibres, vectra fiber or pbo fiber to make.
Make a method for above-mentioned covering, there are following steps:
Step one, lower fiber cloth is laid in plane, lower fiber cloth pastes heating wire, makes heating wire form latticed heating wire intertexture net;
Step 2, arrange a temperature sensor at each latticed heating wire point of crossing, temperature sensor is connected with control setup signal;
Step 3, electric supply installation and control setup and heating wire are connected to form current supply circuit;
The working temperature range of step 4, setup control device, opens electric supply installation and debugs;
Step 5, on heating wire interweaves online covering fiber cloth, and it is bonding that two-layer fiber cloth is formed;
Step 6, respectively function tunic and upper function tunic under side bonds on the downside of lower fiber cloth and in upper fiber cloth;
Step 7, laminating operation is carried out to the film after bonding, again debug after completing.
In step one, the joint of heating wire carries out phosphoric acid process.
The invention has the beneficial effects as follows, covering with function of temperature control of the present invention and preparation method thereof, temperature actuated process is simple and convenient, realize intelligent operation, efficiency is high, temperature coverage-200 DEG C ~ 100 DEG C, actv. solves structural failure that huge inflatable aircraft skin structure brings due to complex environments such as high temperature, snow and ice cover causes the problems such as gravity increase.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As depicted in figs. 1 and 2, a kind of covering with function of temperature control of the present invention, comprise the upper function tunic 1, upper fiber cloth 2, heating wire intertexture net 3, lower fiber cloth 4 and the lower function tunic 5 that fit together of high pressure successively from top to bottom, also have electric supply installation 6 and at least one temperature control module 7, described electric supply installation 6 and temperature control module 7 form current supply circuit with heating wire intertexture net 3.
Further, the heating wire of described heating wire intertexture net 3 is latticed, and latticed heating wire is equal interval 30cm in the horizontal and vertical directions.
Concrete, described temperature control module 7 comprises at least one temperature control sensor and control setup.
Described upper function tunic is anti-aging film (PI, PVF, ETFE, PCTFE, ECTFE, PTFE), Obstruct membrane (EVOH, PVDF) or blooming (gold-plated/silver-plated/aluminize anti-aging film), and lower function tunic is coated film (PU, TPU, thermoplastic polyester, thermoplastic elastomer, rubber).
As preferably, described upper fiber cloth 2 and lower fiber cloth 4 adopt high-tenacity polyethylene fibre, Kafra fiber (kevlar), poly-ester fibres (PET), vectra fiber (vectran) or pbo fiber to make.When covering is in contraction state, soft high strength membrane Material Relaxation, when stressed-skin construction is in extended state, the tight load of soft high strength membrane material.Adopt two-layer fiber cloth to substitute common utricule covering in the present invention, through mechanical analysis and verification experimental verification, the force-bearing property of this kind of stressed-skin construction and stability all can meet operating needs.
Make a method for above-mentioned covering, there are following steps:
Step one, lower fiber cloth 4 is laid in plane, lower fiber cloth 4 pastes heating wire, makes heating wire form latticed heating wire intertexture net 3;
Step 2, arrange a temperature sensor at each latticed heating wire point of crossing, temperature sensor is connected with control setup signal;
Step 3, electric supply installation 6 and control setup and heating wire are connected to form current supply circuit;
The working temperature range of step 4, setup control device, opens electric supply installation 6 and debugs;
Step 5, on heating wire intertexture net 3, cover fiber cloth 2, and it is bonding that two-layer fiber cloth is formed;
Step 6, respectively function tunic 5 and upper function tunic 1 under side bonds on the downside of lower fiber cloth 4 and in upper fiber cloth 2;
Step 7, laminating operation is carried out to the film after bonding, again debug after completing.
Further, in step one, the joint of heating wire carries out phosphoric acid process.
Stressed-skin construction surface will have enough protections in case fiber cloth is impaired and performance weakens, and arranges function tunic respectively, while ensureing that fiber cloth is not impaired, improve stressed-skin construction intensity further in the upper and lower both sides of stressed-skin construction.It is high pressure bonding structure between membrane structure, while there is higher-strength, internal placement heating wire, can control effectively to temperature, in case the stressed-skin construction performance variation caused too high or too low for temperature, thus make skin material tackle the external temperature environment of various complexity, thus expand its application, improve its field of application.
The above-mentioned covering with function of temperature control carries out an operation for temperature control, is specially:
1) space temperature residing for the temperature sensor perception skin material inside fiber cloth, on heating wire, and pass gained temperature data back control setup;
2) control setup is by the reading to temperature, analysis, and whether Based Intelligent Control connects electric supply installation 6.
3) if temperature is lower than-65 DEG C, electric supply installation 6 is connected, and heating wire is stressed-skin construction heating; If temperature is higher than-55 DEG C, supply disconnecton, covering keeps space temperature.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification sheets, must determine its technical scope according to right.
