The utility model discloses in combined material lamination board covering forming process, lay thickness between one -way area in layer and fabric for the carbon nanotube film of micron order, the carbon nanotube film dipes to the resin between the layer in behind the curing molding. This structure has given combined material skin structure good electrically conductive ability, can the prevent static electricity arcing, avoid suffering the thunderbolt, and promoted the security of aircraft structure.
Description
Technical field
This utility model belongs to Aviation Composite Structure design field, especially relates to a kind of antistatic multiple
Condensation material eyelid covering ply angles.
Background technology
At present, the eyelid covering being widely used in aviation aircraft is composite material laminated board and reinforcement co-curing
The Material Stiffened Panel structure of molding.The conductive capability of composite is poor, after producing electrostatic, if cannot lead to
Cross the release of rational path, the safety of aircraft can be caused high risks.After running into contrary electric charge,
Spark may be produced, run into goods or fuel oil, cause burning or blast；Radio in interference body
Normal work, loses structural intergrity after even subjecting to thunderbolt.
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of antistatic composite material eyelid covering, if including
Dried layer one-way tape and be laid on the fabric on outermost layer one-way tape, it also includes layer of conductive film, described
Conductive film is laid between described fabric and described outermost layer one-way tape.
Preferably, described conductive film includes carbon nano-tube film.
In such scheme preferably, the thickness of described carbon nano-tube film is 10 μm～50 μm.
In such scheme preferably, described conductive film includes Graphene.
The most relatively, this utility model, will during composite material laminated board covering forming
Thickness is that micron-sized carbon nano-tube film is layed in layer between one-way tape and fabric, carbon nanometer after curing molding
Pipe thin film is immersed in interlayer resin.This structure imparts the conductive capability that composite material skin structure is excellent,
It is possible to prevent electrostatic arcing, it is to avoid be struck by lightning, promotes aircaft configuration safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of a preferred embodiment of this utility model antistatic composite material eyelid covering.
Wherein, 1 is one-way tape, and 2 is conductive film, and 3 is fabric.
Detailed description of the invention
Clearer, below in conjunction with this reality for the purpose making this utility model implement, technical scheme and advantage
With the accompanying drawing in new embodiment, the technical scheme in this utility model embodiment is carried out more detailed retouching
State.In the accompanying drawings, the most same or similar label represents same or similar element or has identical
Or the element of similar functions.Described embodiment is a part of embodiment of this utility model rather than all
Embodiment.The embodiment described below with reference to accompanying drawing is exemplary, it is intended to be used for explaining this practicality
Novel, and it is not intended that to restriction of the present utility model.Based on the embodiment in this utility model, ability
The every other embodiment that territory those of ordinary skill is obtained under not making creative work premise, all belongs to
Scope in this utility model protection.Below in conjunction with the accompanying drawings embodiment of the present utility model is carried out specifically
Bright.
In description of the present utility model, it is to be understood that term " " center ", " longitudinally ", " laterally ",
"front", "rear", "left", "right", " vertically ", " level ", " top ", " end " " interior ", " outward " etc. refer to
The orientation shown or position relationship, for based on orientation shown in the drawings or position relationship, are for only for ease of description originally
Utility model and simplification describe rather than indicate or imply that the device of indication or element must have specific side
Position, with specific azimuth configuration and operation, therefore it is not intended that restriction to this utility model protection domain.
Below by embodiment, this utility model is described in further details.
This utility model provides a kind of antistatic composite material eyelid covering, the most relatively, this reality
With novel during composite material laminated board covering forming, it is micron-sized carbon nano-tube film paving by thickness
It is located between layer one-way tape or fabric, during after curing molding, carbon nano-tube film is immersed in interlayer resin.This knot
Structure imparts the conductive capability that composite material skin structure is excellent, by metal connecting piece by itself and other structures
Connect, be possible to prevent electrostatic arcing, it is to avoid be struck by lightning, promote aircaft configuration safety.
Concrete, as described in Figure 1, this utility model antistatic composite material eyelid covering, if unidirectional including dried layer
With 1 and the fabric 3 that is laid on outermost layer one-way tape, and also include layer of conductive film 2, described
Conductive film 2 is laid between described fabric 3 and described outermost layer one-way tape 1.
In the present embodiment, described conductive film includes carbon nano-tube film.The thickness of described carbon nano-tube film
It is 10 μm～50 μm.It is understood that carbon nano-tube film is as emerging quasi-one-dimensional nanometer material,
The special constructions such as its hollow structure, big specific surface area and high draw ratio so that it is there is many unusual things
Physicochemical character, such as conduction, printing opacity, flexibility and absorption etc..The thickness of 10 μm～50 μm was set both
The eyelid covering demand to intensity, thickness, weight etc. can be met, can meet again its when with one-way tape curing molding,
There are enough amounts to be immersed in interlayer resin and arrived the requirements such as there is excellent conductive capability.
In an alternate embodiment, described conductive film can also is that Graphene.As have now been found that
A kind of novel nano-material that the thinnest, maximum intensity, electrical and thermal conductivity performance are the strongest, uses the Graphene of monolayer
Eyelid covering performance requirement can be met as conductive film, financial burden will not be formed again.
Conductive film is arranged in eyelid covering by the present embodiment, mainly comprises the steps that
First, according to eyelid covering laying needs, on mould, lay the 1st layer arrives n-2 layer one-way tape successively,
During composite material laminated board laying, by carbon nano-tube film lay in top layer fabric n and one-way tape n-1
Between, form the ply angles of preforming.
Afterwards, by preforming ply angles according to the molding mode of laminate, hot-press solidifying molding.
The composite material skin structure using above step to prepare has excellent conductive capability, is possible to prevent machine
Body electrostatic hazard, it is to avoid be struck by lightning, improves housing construction security performance.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, rather than
It is limited.Although this utility model being described in detail with reference to previous embodiment, this area general
Lead to and skilled artisans appreciate that the technical scheme described in foregoing embodiments still can be repaiied by it
Change, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make phase
The essence answering technical scheme departs from the spirit and scope of this utility model each embodiment technical scheme.
