Description
Technical field
The invention is related to a kind of technique for being glued bondline thickness using self-control rubber cover board control, is used for aircraft skin
The bondline thickness control technique being glued with stiffening plate.
Background technique
Siding due to covering and reinforces template face in Bonding Process in the aircraft tail wing tip horizontal tail stabilization of certain model
Tolerance is big, be easy to cause the cooperation between covering and stiffening plate uneven, so as to cause the covering in Bonding Process and stiffening plate
Between splicing bondline thickness it is widely different, have exceeded code requirement value, cause part to delay to succeed in developing, not only cause
Very huge economic loss, and lead to being discontented with for client.
Summary of the invention
The invention technical problems to be solved are to provide a kind of using self-control rubber cover board control splicing bondline thickness
Technique, the equal pressing plate of the technology utilization rubber realizes being uniformly distributed again for hot pressing pressure tank, acts directly on reinforcement with pressure
It is compared on plate, the influence of positive between stiffening plate and covering to the thickness of glue-line is reduced, so that it is uniform to obtain thickness
Glue-line.It using the easy to operate of the equal pressing plate, accurate positioning and conveniently checks oneself, process and result are visual controllable effect
Fruit improves the quality and working efficiency of product.
In order to solve the above problem, the specific technical solution of the invention is as follows: a kind of to be controlled using self-control rubber cover board
It is glued the technique of bondline thickness, comprising the following steps:
1) it makes equal pressing plate: stiffening plate A being placed at pre-glued covering, in the non-sulphur of stiffening plate upper surface laying several layers
Change rubber, in one layer of dry carbon fibre fabric of bottom first layer upper surface laying of half finished rubber, half finished rubber and carbon fiber
The area for tieing up fabric is greater than the top surface area of stiffening plate A, and surrounding redundance is laid in pre-glued covering upper surface；Whole envelope system
Vacuum bag, and move in autoclave, then pass through curing process, forms equal pressing plate after removing stiffening plate A；
2) glue film is taped against on pre-glued covering, then stiffening plate B is placed on glue film, successively spread on stiffening plate B
Pasting one layer of removing cloth and one layer has hole isolation film, finally buckles equal pressing plate, and removing cloth is pressed with the surrounding for having hole isolation film stretching
Plate；
3) pressing plate uses pin to connect positioning with stiffening plate B；
4) the whole envelope vacuum bag processed by step 2 and 3), and move in autoclave, to application pressure at the top of equal pressing plate, and
Heating is solidified, up to the covering bonding layer of uniform thickness after solidification；
Compared with the stiffening plate B described in the step 2 of stiffening plate A described in step 1), the big 1.5 ~ 2mm of surrounding size, thickness is high
There is stiffening plate to hide slot for 0.3mm, resulting equal pressing plate.
The solidifying pressure of equal pressing plate described in step 1) is 310 ± 30KPa, and solidification temperature is 130 ± 5 DEG C.
Curable adhesive layer pressure described in step 4) is 210 ± 30KPa, and solidification temperature is 121 ± 5 DEG C, the glue-line after solidification
With a thickness of 0.05 ~ 0.5mm.
This is glued the equal pressing plate of technology utilization rubber of bondline thickness to the equal again of pressure using self-control rubber cover board control
Even distribution, it reduces pressure and acts directly in stiffening plate reason and reinforce template face bring pressure and be unevenly distributed, to obtain
Obtained glue-line in homogeneous thickness.The equal pressing plate using easy to operate, be easy to grasp, manufacturing cost is low, convenient for promoting, the technology
A large amount of production cost is saved, while realizing the breakthrough of adhesive bonding technique.

Fig. 1 is equal platen manufacturing schematic diagram.
Fig. 2 is the equal pressing plate schematic diagram to complete.
Fig. 3 is the process schematic representation for being glued bondline thickness using self-control rubber cover board control.
Specific embodiment
A kind of technique for being glued bondline thickness using self-control rubber cover board control, comprising the following steps:
1) it makes equal pressing plate: stiffening plate A1 is placed at pre-glued covering 2, laying several layers are not in stiffening plate upper surface
Vulcanized rubber 3, in the dry carbon fibre fabric 4 of one layer of the bottom first layer upper surface laying of half finished rubber 3, half finished rubber 3
It is greater than the top surface area of stiffening plate A1 with the area of carbon fibre fabric 4, surrounding redundance is laid in table on pre-glued covering 2
Face；It is whole to seal vacuum bag 5 processed, and move in autoclave, then pass through curing process, solidifying pressure is 310 ± 30KPa, solidification
Temperature is 130 ± 5 DEG C, forms equal pressing plate 6 after removing stiffening plate A1；
2) glue film 7 is taped against on pre-glued covering 2, then stiffening plate B8 is placed on glue film 7, on stiffening plate B8 according to
One layer of removing cloth 9 of secondary paving and one layer have hole isolation film 10, finally buckle equal pressing plate 6, removing cloth 9 and have the four of hole isolation film 10
Week stretches out equal pressing plate 6；
3) pressing plate 6 uses pin to connect positioning with stiffening plate B8；
4) whole by step 2 and 3) seals vacuum bag 5 processed, and moves in autoclave, to applying pressure at the top of equal pressing plate 6,
Pressure value is 210 ± 30KPa, and heats and solidified, and solidification temperature is 121 ± 5 DEG C, and uniform thickness is 0.05 to obtain the final product after solidification
The covering bonding layer of ~ 0.5mm.
Wherein compared with the stiffening plate B8 described in the step 2 of stiffening plate A1 described in step 1), the big 1.5 ~ 2mm of surrounding size,
There is stiffening plate to hide slot, and the cooperation with equal pressing plate and stiffening plate for the high 0.3mm of thickness, resulting equal pressing plate 6.
In hot pressing in-tank-solidification, pressure acts on equal pressing plate first, and equal pressing plate realizes certain buffering and again to pressure
Secondary distribution, so that the pressure acted in stiffening plate is uniform, so that the bondline thickness between stiffening plate and covering is equal
It is even, up to the covering bonding layer of uniform thickness after solidification.
