It connects, overlapping regions (6) resin bonding, and the sunk screw (5) by passing through wave transparent window (2) periphery mounting hole is connected firmly in mounting plate
Upper (1)；Entire antenna cover outer surface sprays filter function material.But the size of the wave transparent window of the antenna house be it is fixed, can not
It is adjusted as needed, needs to make different size of wave transparent window for the needs in different wave transparent regions, production cost is higher.
Summary of the invention
The technical problem to be solved by the present invention is to the antenna house of existing middle part wave transparent, its wave transparent region is unable to flexible modulation,
A kind of compound antenna house and preparation method thereof is provided thus.
The technical scheme is that compound antenna house, it includes aramid fiber honeycomb, is located at aramid fiber honeycomb upper and lower surfaces
The wave permeation layer of intermediate region, and the not wave permeation layer positioned at aramid fiber honeycomb upper and lower surfaces neighboring area, the wave permeation layer centre are equipped with
Level runs through the hollow sandwich of wave permeation layer, and the not wave permeation layer includes the bar shaped rib of aramid fiber honeycomb side of being laid in, the item
The upper and lower ends of shape rib have the hollow cavity that extends and be mated with to wave permeation layer, in the hollow cavity equipped with it is hollow
The hollow slideway of interlayer docking, it is conformal in the hollow slideway to be fitted with horizontally slidable sliding block, the sliding block side connection
There are waveform carbon-fibre strips, sliding block will drive waveform carbon-fibre strips to protrude into hollow cavity when injecting flow media into vacuum slide way
It is interior.
Wave permeation layer is glass mat in above scheme.
The preparation method of compound antenna house, it is the following steps are included: (1), as required size cut aramid fiber honeycomb；(2),
Glass mat is made, is cut into and requires size；(3), not wave permeation layer is made, is cut into and requires size；(4), it is laid on honeycomb
Glue film re-lays glass mat；(5), whole to be put into vacuum bag, priming by vacuum curing molding；(6), by not wave permeation layer
Bar shaped rib is fixed in the cellular side of aramid fiber, hollow cavity is docked with wave permeation layer it is bonding so that hollow slideway with it is hollow
Interlayer docking；(7), gas or liquid are injected to hollow slideway, so that sliding block is mobile to wave permeation layer, waveform carbon-fibre strips is driven to stretch
Enter in hollow sandwich, changes the wave transparent region of wave permeation layer.
Glass mat described in above scheme is made by alkali-free glass fiber cloth and unsaturated polyester resin.
Carbon fiber board described in above scheme is made by carbon cloth and unsaturated polyester resin.
The beneficial effects of the invention are as follows glass mat is used, as electromagnetic wave transparent material, carbon-fibre strips are used as not electromagnetic wave transparent material,
The self weight of antenna house is reduced, intensity is high, and corrosion-resistant, the structure of wave permeation layer and wave permeation layer does not design the wave transparent region so that wave permeation layer
It can be adjusted, adapt to the demand of different wave transparent areas, reduce production cost.
