Laying lift, be compacted with the outside of liner plate 3 with type, then lift housing side laying, be together placed into bonding angle mold 4 and SS face-pieces
Between body 5, liner plate 3 is adjusted, makes the SS faces trailing edge bonding angle laying 6 with liner plate 3 sturdy with Nian Jie angle mold 4 and SS face-pieces body 5,
Liner plate 3 is fixed with fixture 7, then bubble is driven out of with roller.
(4) after solidification is stripped 2 hours, bonding angle laying 6 solidifies, and removes bonding angle mold and release cloth, and band PS faces are made
The SS faces trailing edge bonding angle of trailing edge liner plate.
Embodiment two
The present embodiment is used to prepare the PS faces trailing edge bonding angle with SS faces trailing edge liner plate, and its specific preparation method includes following
Step：
(1) after the completion of making the laying of SS faces trailing edge liner plate blade SS faces shell layer, into auxiliary material arrangement stage, the laying demoulding
After cloth, the wide biaxially cloth of 3 layers of 180mm is laid within blade SS face-piece body trailing edge L8m~L14m parting lines, then with blade
SS face-piece body one forms, produce SS faces trailing edge liner plate.
(2) after resin precuring, vacuum bag film is opened, is drawn SS faces trailing edge liner plate periphery 30mm release cloth with wallpaper knife
Open, and stuck up out from one jiao, tear and drag release cloth and separate SS faces trailing edge liner plate and SS face-piece bodies, remove the release cloth on liner plate, will
Corner cutting is neat, and the corner cutting especially at liner plate parting line is smooth.
(3) PS faces trailing edge bonding angle is made
A, the wide vacuum bag films of 1 layer of 400mm are laid, then are laying the wide biaxially cloth of 1 layer of 300mm thereon, uniformly on
The resin mixed, fiber cloth is impregnated with using roller, drives bubble out of, repeat above-mentioned action, lay 5 layers of biaxially cloth altogether,
And width staggered floor 5mm between layers, length direction staggered floor 50mm, produce bonding angle laying；
B, trailing edge is bonded on angle mold and lays release cloth with glue spraying, bonding angle mold is then fixed on PS face-piece body methods
Lan Shang；
C, SS faces trailing edge liner plate parting line side is directed at bonding angle laying center line, and first will presses close to be bonded the paving of angle mold in advance
Layer lifts, and is compacted with liner plate with type, then lifts housing side laying, is together placed between bonding angle mold and housing, adjustment lining
Plate, the PS faces trailing edge bonding angle laying with liner plate is shown consideration for Nian Jie angle mold and PS face-pieces real, fix liner plate with fixture, use roller
Son drives bubble out of；
(4) after solidification is stripped 2 hours, the solidification of bonding angle laying, bonding angle mold and release cloth is removed, is made with SS faces
The PS faces trailing edge bonding angle of trailing edge liner plate.
The SS faces trailing edge bonding angle of the band PS faces trailing edge liner plate respectively obtained from above-mentioned two embodiment and with SS faces trailing edge
The PS faces trailing edge bonding angle of liner plate can be seen that：The bonding angle with liner plate, is U-shape structure.The outer shape of the U-shape structure with
Corresponding blade bonding region inner shape matches, and the liner plate is set on the inside of one side or adjacent both sides along U-shape structure.
Wherein, bonding angle and liner plate thereon are impregnated with the fiber cloth superposition solidification of resin by multilayer and are made.Specifically, bonding angle includes
4~7 layers of fiber cloth for being impregnated with resin, liner plate include 1~3 layer of fiber cloth for being impregnated with resin.
By the present invention in that making bonding angle with liner plate, existing bonding angle poor location can be overcome, collapse, be layered etc. and be scarce
Fall into, bonding angle quality is substantially increased, especially close to rear side with type, it is ensured that bonding agent thickness reaches design requirement.
The present invention make liner plate technique both can as in embodiment one with the housing hand pasting forming after precuring, also can be such as
Together irrigated with housing in embodiment two it is prefabricated form, liner plate processed can also be turned over by being bonded angle mold and formed, technological design is closed
Reason, workable, production efficiency is high.
Certainly, the bonding angle that prepared by the present invention can also remove liner plate, work according to operating space size after bonding angle solidification
Skill strong operability.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, this
Art personnel make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above, all fall within this hair
In bright protection domain.
