Abstract
The invention relates to an auxiliary tool for composite material edge sealing and a sealing method, belonging to the technical field of manufacture of composite materials. An arc groove is formed at one side of an auxiliary sealing tool body, and when the thickness of the edge of the composite material piece is changed, the useful area of the arc groove is also changed. The self-made sealing tool is adopted, so that the cost is effectively reduced, the edge sealing thickness is controllable, no burr is formed on the edge, the follow-up trimming is not required, and the working efficiency is greatly improved; after the auxiliary tool is used, the improvement effect is remarkable, the edge sealing quality is perfectly controlled, no burr is formed on the edge of the composite material workpiece, crack expansion is effectively avoided, the thickness is uniform, and the customer requirement is met; and the auxiliary tool can be easily operated, and the working efficiency is greatly improved while the sealing quality of the edge is ensured.
Description
Technical field
The invention belongs to manufacture technology of composite material field, especially a kind of composite edge seal aid and close
Encapsulation method.Specifically by the application of mathematical model in production practices, complete composite product edge seal.
Background technology
Current generation, on aircraft, the utility ratio of composite reaches more than 40%, after preventing composite material parts cutting
Edge produces the unfavorable factors such as secondary stratification, cracks can spread and edge make moist to be occurred, can carry out close to composite product edge
Envelope.Edge is sealed by conventional edge sealing technology method for dipping edge sealing agent with brush.This process limitation is big, only
Can towards the less edge sealing agent of viscosity, and seal the most thorough, it may appear that holiday and the uneven phenomenon of coating, traditional handicraft side
Part following process, it cannot be guaranteed that the thickness of edge sealing agent after edge seal, is caused extreme influence by method.Traditional handicraft is applied to
In technique for aircraft composite product edge seal, its inferior position is exaggerated:
1, novel adhesive viscosity is very big, and adhesive produces adhesion on hairbrush, causes part edge uneven thickness, it is impossible to
Meet customer requirement.
2, edge sealing efficiency is low, it is impossible to ensure that multiple material product completes edge seal within this novel adhesive kettle dress life-span.
3, the follow-up finishing cost time is long, has a strong impact on work efficiency.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the present invention provides a kind of sealing close for composite edge to assist
Instrument.
It is a further object of the present invention to provide and a kind of utilize this sealing tool to carry out the side sealed for composite edge
Method.
It is an object of the invention to be achieved through the following technical solutions: a kind of composite edge seal aid, its
It is characterised by: the side of this sealing aid body is shaped with arc groove；Described arc groove size and attachment glue
Composite product edge thickness match.
A kind of composite method for sealing edge, it is characterised in that step is as follows:
(1) founding mathematical models, simulates edge sealing process: utilize CATLA software by the edge seal process in actual production
Simulation, input is treated the composite product parameter of edge sealing, is set up threedimensional model；
(2) quantitative analysis, sets up functional equation: by three-dimensional model simplifying, obtains edge seal two-dimensional numerical model；And it is right
The adhesive of edge sealing carries out quantitative analysis,
In conjunction with trigonometric function knowledge, draw equation: R=H2/8D+D/2
Wherein R: seal the radius of aid body leading edge circular groove
The thickness of H: composite product；
D: Adhesive thickness；
(3) analytic equation, opening relationships formula；
In above-mentioned equation: the thickness H and Adhesive thickness D of composite product thus can calculate close with fixing quantity
The radius D of envelope aid body leading edge circular groove；
(4) filter out conventional exemplary value, produce the composite edge seal aid of conventional model, specifically select
With R=1.1mm, R=2.3mm, R=5.3mm, utilize this composite edge seal aid to carry out edge seal, control
The thickness of adhesive is all in the range of 0.3-0.8mm.
Beneficial effects of the present invention: the present invention uses such scheme, by homemade sealing tool, effectively reduces cost,
And it is controlled to achieve edge seal thickness, it is ensured that edge impulse-free robustness, it is not necessary to follow-up finishing, substantially increase work efficiency.Real
Shi Hou, improvement effect is obvious, and edge seal quality obtains perfect control, and composite product edge impulse-free robustness again produces, effectively
Avoid cracks can spread, and thickness is uniform, meets customer requirement；And processing ease, while ensureing edge seal quality, greatly
Amplitude improves work efficiency.

Fig. 1 is the structural representation sealing aid.
Fig. 2 is the three-dimensional mathematical model modeling figure of method for sealing edge.
Fig. 3 is the two-dimensional numerical model modeling figure of method for sealing edge.
In figure 1, seal aid body；2. arc groove；3, composite product；4, adhesive；5, pressure sensitive adhesive tape.
Detailed description of the invention
A kind of composite edge seal aid, as it is shown in figure 1, in the side system of this sealing aid body 1
There is arc groove 2；Arc groove 2 size matches with the composite product edge thickness of attachment glue.
A kind of composite method for sealing edge, step is as follows:
(1) founding mathematical models, simulates edge sealing process: utilize CATLA software by the edge seal process in actual production
Simulation, sets up threedimensional model, as it is shown on figure 3, pressure sensitive adhesive tape 5 is to prevent adhesive following current in edge seal process in figure
On composite product, cleaning difficulty.
(2) quantitative analysis, sets up functional equation: by three-dimensional model simplifying, obtains edge seal two-dimensional numerical model；Such as figure
Shown in 3, and the adhesive of edge sealing is carried out quantitative analysis, in conjunction with trigonometric function knowledge, draws equation:
R=H2/8D+D/2
Wherein R: seal the radius of aid body leading edge circular groove
H: composite material parts thickness (this type composite material parts thickness is 1.5～5.6mm)
