Embodiment
In order to better understand according to the aircraft metal resistant cementing structure product weight losing method of the present invention program, tie below
Attached drawing is closed to be further elaborated a preferred embodiment of the aircraft metal resistant cementing structure product weight losing method of the present invention
It is bright.
As Figure 1-Figure 2, aircraft metal resistant cementing structure product weight losing method provided by the invention, for aircraft gold
Belong to the Weight control of durable cementing structure product, include the following steps：
S1, chooses overweight metal resistant cementing structure product；
S2, analyzes the weightening process of metal resistant cementing structure product described in S1；
S3, chooses from the weightening process selected by S2 and is glued process as loss of weight process；
S4, Theoretical Design control glue consumption, draw the weight range of glue consumption；
S5, designs durable cementing structure product technique glue consumption loss of weight experiment；
The durable cementing structure part weight scope of control is drawn by S1-S5.
In the process step for the aircraft metal resistant cementing structure product weight losing method that the invention described above provides, chosen in S3
It is to keep the intensity of aircraft metal resistant cementing structure product to be glued process as the foundation of loss of weight process；Theoretical Design control in S4
The foundation of glue consumption processed includes glue-joint strength；Durable cementing structure product technique glue consumption loss of weight experiment is contrast test in S5.
Durable cementing structure product technique glue consumption loss of weight experiment includes the following steps in S5：S5-1, three groups of design are identical
Structural member, and weigh to structural member；S5-2, in S5-1 structural member carry out glue spraying operation, and to glue spraying operate after
Structural member is weighed；S5-3, structural member are glued fitting；S5-4, is further handled structural member；S5-5, weighs and draws experiment
Data.
The glue spraying that three groups of structural members carry out is operated in S5-2 and is respectively：One group is the disposable glue spraying of whole face；One group is whole
The disposable glue spraying in face and carry out inhale glue operation；One group is divided gradual glue spraying for branch and carries out suction glue according to glue spraying order.Wherein, on
Involved suction glue operation used tool is suction gummed paper in stating.
Among above-mentioned steps, inhale glue material and be used in pre-suction glue or curing process, can quantify and suction out Excess resin in blank,
And there is certain air permeability energy.Inhale glue material and have and inhale rubber mat, glass cloth etc., inhale glue material unit area resin absorption with material and
It is different.Common rubber mat of inhaling inhales material trademark：AIRWEAVE.S；Individual layer inhales glue weight：150~200 (g/m2)。
During specific use, aircraft metal resistant cementing structure product weight losing method provided by the invention is applied
In the design production process of the metal bonding product of aircraft.
First, the weight configuration personnel in Conceptual Aircraft Design Process propose according to the overall weight loss of weight demand of aircraft
The weight of glue consumption needed for metal bonding product is ± the 2.5% of part weight.Metal bonding product on above-mentioned aircraft
Totally 8, all overweight, maximum overweight amplitude reaches 12%, and minimum overweight amplitude reaches 4%.
Secondly, it is designed analysis to being glued product splicing interface.Be glued product by adhesive and adherend surface by
Adhesive attraction is formed.A complicated boundary layer is formed between adherend surface and adhesive, is illustrated in figure 2 splicing boundary layer
Schematic diagram.Boundary layer is by adherend 1 and its superficial layer (such as anodization layer 2), adsorption layer (such as empty gas and water, impurity), close quilt
The primer layer 3 and glued membrane 4 of the anodization layer 2 of viscous thing 1 form.
Again, it is glued design and combines wetting qualities requirement.Adhesive to the good moistening on adherend surface be to be formed it is excellent
The necessary condition of product.Adhesive is when the expansion of adherend surface wettability reaches balance：
γ S=γ SL+ γ L cos θ (1-1)
In formula：γ S --- adherend surface energy；
γ L --- liquid adhesive surface tension；
γ SL --- interfacial tension between adherend and liquid adhesive；
θ --- contact angle.
Found out by formula (1-1), to obtain good interface, it is necessary to reach it is following some：
A) 4/ primer layer of glued membrane, 3/ anodization layer will reach good compatibility；
B) contact angle θ≤0；
C) adherend 1 should have high surface energy.High surface energy helps to reduce the contact between glued membrane 4 and adherend 1
Angle, improves wet performance of the adhesive to adherend 1.
Increase pre-suction glue process.On the premise of meeting that being glued product is glued the design wetting qualities requirement at interface, carry out
Loss of weight technological work, increases pre-suction glue process after glued membrane is applied, and the splicing design for proving to meet product by test of many times will
Ask, and significantly reduce the weight of product.
