Description
Technical field
The present invention relates to fibre reinforced composites processing and forming field, and in particular to one kind be used for composite product into
The equal pressing plate flexible connecting method of type.
Background technology
During prepared by composite product, the surface light with identical size and dimension is laid on product blank
Sliding metal or composite board is widely used as equal pressing plate.Especially prepared with autoclave technique in composite material
The process such as pre-compacted, solidification in, equal pressing plate is used in pre-compacted and solidification process, when vacuumizing（Pressurization）During with heating,
Pressure will be pressed in layers of material on blank by equal pressing plate and pass to blank, be compacted its composite blank, discharge
Bubble, low molecule and Excess resin, produce satisfactory smooth surface product；Heat is more uniformly delivered to product hair
On base, it is ensured that curing rate is suitable.
For the composite product that type face is complicated, such as product with boss, flange, groove and sandwich structure,
The requirement of complex profile product can not be met according to traditional equal pressing plate.The equal pressing plate of piecemeal splicing, stitching portion is easily formed
Fold is caused on product；Using rubber soft mode and overall pressing plate can not all ensure product blank with equal pressing plate matching somebody with somebody well
Close, easily form bridge formation on product blank or pressure is uneven, cause the internal soundness problems such as the local rich resin of product.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art part to be used for complex profile composite product there is provided one kind
The equal pressing plate connection method of shaping, the requirement of pressure transmission uniformity when meeting forming parts, it is ensured that the inside of part and outer
Portion's quality.
A kind of equal pressing plate flexible connecting method being molded for composite product, when composite is molded, by prepreg
Product blank is discharged on mould upper berth, peelable material is laid on prepreg, product complex profile is decomposed into simply
Type face, correspondence simple type face cuts into equal pressing plate correspondingly sized, then the equal pressing plate of piecemeal is laid on product blank, root
The flexible material consumption for determining to use according to the gap between equal pressing plate, is put into equal pressing plate in strip or web-like by flexible material and splices
Completed in seam after flexible material filling, lay gas permeable material, finally accomplish fluently vacuum bag.
Sandwich material is provided between peelable material and prepreg.
Composite shaping, uses autoclave forming process, OOA moulding process, liquid molding process, Wrapping formed
Technique.
The equal pressing plate uses metal or non-metallic material, and temperature, pressure can be uniformly transferred when composite is molded
To the sheet material or frock of product blank.
The flexible material can be rubber strip after plasticating or the silicon rubber that mixes according to a certain ratio.
The method of the present invention, simple type face, such as plane, cambered surface, correspondence simple type face are decomposed into by product complex profile
Equal pressing plate is cut into correspondingly sized, the equal pressing plate of piecemeal leaves certain surplus.Before product cure package, by the equal pressing plate of piecemeal
It is laid according to its correspondence type face on product blank and isolated material.Flexible material is placed on what splicing was produced in strip or package
Among gap, gas permeable material and encapsulated vacuum bag are then laid.With the raising of vacuum in vacuum bag, flexible material is by pressure
Among effect filling to the gap between equal pressing plate.The function that wherein flexible material can play transmission pressure, ecad face is required.
When temperature rise or under pressure, flexible material fills up equal pressing plate splicing gap；As temperature continues to raise, flexible material
Start solidification（Crosslinking）, with the progress of curing reaction, the intensity that flexible material can keep certain no longer softens, and then ensures
Pressure is uniformly distributed.Flexible material can be removed after solidification, recover the state of the equal pressing plate of piecemeal.Flexible material is in normal temperature
It can deform, conveniently cut into definite shape.Flexible material is when solidifying maximum temperature, and material remains able to transmit pressure.It is soft
Property material can use the prepreg same or like with composite product.
Beneficial effects of the present invention：It ensure that Product Assembly face quality, it is to avoid polishing, reduce operational sequence and be processed into
This, improves product inherent quality, prevents that subregion matrix caused by pressure is uneven is loose.Prevent because equal pressing plate is spelled
Seam and the gauffer produced, it also avoid caused build bridge that be rigidly connected.

Embodiment
Illustrate the present invention below by specific embodiment.
When composite is molded, by prepreg（Fabric）2 discharge into product blank on the upper berth of mould 1, by peelable material 3
It is laid in prepreg（Fabric）On 2.Product complex profile is decomposed into simple type face, such as plane, cambered surface, correspondence simple type
Face cuts into equal pressing plate correspondingly sized, the equal pressing plate 4 of piecemeal is laid on product blank, according to the gap between equal pressing plate
It is determined that the consumption of flexible material 5 used, flexible material 5 is put into the equal splicing seams of pressing plate 4 in strip or web-like.
Flexible material 5 should fill up gap between equal pressing plate, can suitably many a certain amount of flexible materials of filling.Complete flexible material
After the filling of material 5, gas permeable material 6 is laid, vacuum bag 7 is finally accomplished fluently.When preparing blank, sandwich material 8 is when laying prepreg 2
Lay in place.
