The shielding layer is a carbon cloth with shielding effect, and the wave-transmitting bearing layer, the strippable cloth layer, and the shielding layer included in the body are integrally formed, and the integrally formed means that the three-layer structure is an integral composite structure. The invention innovatively proposes a skin composite structure in which a wave-transmitting bearing layer, a peelable layer, and a shielding layer are integrally formed, and the bonding force is controlled by the peelable layer, so that the shielding layer can be peeled off, so that the shielding state changes the wave transmission. When it is in the state, it only needs to peel off the skin and shielding layer, which greatly reduces the cycle and cost compared with the new production section. At the same time, the peelable layer, the wave-transmitting carrier layer and the shielding layer are integrated into the composite structure design, which does not affect the shielding state. Product performance and use, use effect is good.
Description
Technical Field
The invention belongs to the technical field of aircraft structures, and particularly relates to a shielding wave-transmitting universal skin structure based on a strippable shielding layer.
Background
For aircraft structures, there are generally two states, shielding and wave-transparent. The structure has shielding requirements on electromagnetic environment in a shielding state, and the installation position of the measuring instrument, such as a head cover and other structures, has wave-transmitting requirements in a wave-transmitting state.
When the shielding state is changed into the wave-transparent state, in order to ensure that the measuring system uses the section with the wave-transparent requirement, the skin is different (whether the skin comprises carbon cloth for shielding or not), and the measuring system needs to be put into operation again at present. Therefore, a shielding and wave-transmitting universal skin structure based on a strippable shielding layer is put into use to solve the problems.
Disclosure of Invention
The invention aims to provide a shielding wave-transparent universal skin structure based on a strippable shielding layer, which is used for solving the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a general skin structure of shielding wave transmission based on strippable shielding layer, includes the body, the body is including the wave transmission bearing layer, the wave transmission bearing layer is the bearing layer that no shielding effect is passed through the wave promptly, the strippable cloth layer has been laid to wave transmission bearing layer top, the strippable cloth layer is the strippable layer of control peeling strength, the shielding layer has been laid to strippable cloth layer top, the carbon cloth of shielding layer for having the shielding effect, the wave transmission bearing layer that the body includes, strippable layer, shielding layer integrated into one piece, integrated into one piece means three layer construction formula composite construction as an organic whole.
Preferably, the wave-transparent bearing layer is a wave-transparent bearing structure with a certain thickness, the thickness of the strippable layer is set to be 0.1-0.2 mm, the shielding layer is a carbon cloth with a thickness of 0.1-0.2 mm, and the areas of the wave-transparent bearing layer, the strippable layer and the shielding layer are equal.
Preferably, the wave-transparent carrier layer is a carrier layer which has no shielding effect and is wave-transparent.
Preferably, the peelable layer is a peel layer that controls the peel force.
Preferably, the shielding layer is a carbon cloth having a shielding effect.
