It is highly preferred that the exterior skin layer, inhaling wave layer, reflecting layer, insulating layer, electromagnetic shielding enhancement layer, Inner Mongol cortex Overall thickness is 45mm.
In addition, being used the present invention also provides a kind of forming method of integrated molding cabin structure for having stealthy function The integrated molding cabin structure for having stealthy function provided in above content, specific steps are as follows:
One, first by the exterior skin layer, suction wave layer, reflecting layer, insulating layer, electromagnetic shielding enhancement layer, Inner Mongol cortex in product mould It is successively laid on tool, forms total lamination.
Two, vacuum line is laid on total lamination.
Three, total lamination is closed using vacuum bag film, is then taken out by the way that vacuum pump is intracavitary to total stack-up type It is vacuum-treated.
Four, epoxy resin is imported into the type chamber.
Five, total lamination is kept the temperature, pressure maintaining waits for its solidification.
Six, secondary curing is carried out to total lamination at high temperature.
Seven, total lamination is demoulded from product mold.
The beneficial effects of the present invention are: each layer of material of the molding cabin structure is laid it on product mold Afterwards, the structural integrity can be made to be shaped to cabin using vacuum introducing technology (importing epoxy resin), since cabin is to be integrally formed , the suction wave layer being arranged in structure is made of the foam core or cellular sandwich for having absorbing property, and cooperation has wave Can exterior skin layer, cooperation reflecting layer etc. can reach stealthy function, therefore to stealthy plate than in the prior art and cabin splicing For structure, this structure is avoided using a large amount of components and fastener, is reduced assembly cost, is improved assembly efficiency, Due to reducing segmentation and docking, the manufacturing cost for meeting material members is also reduced, function and structure integration is realized, The weight for reducing product makes product more lightweight, moreover, generates more splicing gap due to avoiding, each to tie Structure layer closely connects, and maintains the continuity of stealth material, to ensure that stealth effect, and this structure is made to improve waterproof Leakproofness can largely reduce cabin stealth material and the risk to fail occurs, and is electromagnetically shielded enhancement layer and has electricity The carbon fibre material Inner Mongol cortex of magnetic shield performance also provides electro-magnetic screen function for cabin.
