Description
Technical field
The present invention relates to forming frock and its forming method that a kind of co-curing is glued shearing sample.
Background technology
As the use of composite is more and more extensive, the quantity and species of cementing structure also increase therewith.One of which
Cementing structure is that bonding agent needs to be molded with polymer matrix composites co-curing, i.e., multiple in uncured prepreg or resin base
Condensation material face adhesive coating to be glued, treats molding component（Including bonding）Afterwards, giving certain pressure solidify under high temperature.But
In order to ensure co-curing bonding quality reliability, carried out in bonding cutting performance of the product predevelopment phase needs in advance to adhesive
Test, due to belonging to rigid material after composite solidification, therefore bonding shearing test specimen size and cementing structure will meet
GB/T 7124-2008。
When current part producer prepares co-curing gluing shearing sample, first forming composite, then by composite processing
As standard size, gluing sample making is carried out.The problem that this preparation method is brought is：Only investigate adhesive and treat viscous examination
Sample physics adhesivity, without take into full account adhesive and composite resin matrix can also crosslink reaction exist it is certain
The gluing effect of chemistry.Sometimes adhesive and resin matrix co-curing also occur that the feelings for being glued failure for discharging small molecule and bringing
Condition, therefore the gluing cutting performance for measuring can not represent the true bonding effect of co-curing cementing structure.This is just follow-up product
The gluing reliability of product brings hidden danger.
The content of the invention
The technical problem to be solved in the present invention is to provide the forming frock that a kind of co-curing is glued shearing sample, to solve mesh
Before there is no composite resin matrix cementing structure co-curing be glued sample forming method problem.
It is the technical problem for solving to exist, the technical solution adopted by the present invention is：First design a kind of co-curing and be glued shearing
The forming frock of sample, including backform and bed die, described backform and bed die are machined with accordingly according to the shape requirements of sample
Shape chamber, bed die and backform are fixed after assembling with fastening bolt；Poroid spew groove is left at described bed die two ends, for many
Cotree fat flows out.
When making sample, the prepreg or fiber cloth that will be cut out are put in bed die according to requirement is laid, and are applied face is glued
Brush pasty state glue is coated with glued membrane, requires to lay the prepreg or fiber cloth that need bonding according still further to laying.Given using bolt
Sample certain pressure, is put in heating furnace and is solidified according to composite cure process.After the completion for the treatment of that sample solidifies, by sample
The demoulding and size required for being machined into is tested.
Beneficial effect
Co-curing of the invention is glued shearing sample preparation method, and the method is easy to operate, and the co-curing of preparation is glued shearing examination
Sample can reflect co-curing bonding cutting performance in actual product.
Brief description of the drawings
Fig. 1 is that co-curing is glued shearing sample preparation frock elevational cross-sectional view；
Fig. 2 is that co-curing is glued shearing sample preparation frock side view cutaway drawing；
Fig. 3 is that co-curing is glued shearing sample preparation frock top view;
In figure, 1 is bed die, and 2 is backform, and 3 is fastening bolt, and 4 is spew groove.
Specific embodiment
The present invention is described further with reference to the accompanying drawings and examples.
As Figure 1-3, a kind of co-curing is glued the forming frock of shearing sample, including backform and bed die, described top
Mould and bed die are machined with corresponding shape chamber according to the shape requirements of sample；Composite sample system is carried out on bed die and on backform
It is standby, after the completion of bed die and backform assembled and be fixed with fastening bolt；Poroid spew groove is left at described bed die two ends,
For Excess resin outflow.
Co-curing is glued the forming method of shearing sample, and its forming step is：
（1）Frock is assembled
1. the inner surface in bed die and backform pastes one layer of release cloth；2. in bed die edge brushing demoulding wax；3. by bed die and backform
Module dresses up sample mould.
（2）Co-curing is glued shearing sample and prepares
1. fabric dividing
The thickness of prepreg cloth or carbon cloth is measured, the number of plies of required cloth is obtained, and cut according to frock size.
2. prepared by composite
Composite is such as prepared using prepreg, prepreg is laid on bed die, and give certain pressure；If fine using carbon
Wei Bu prepares composite, it is necessary to lay one layer of uniform one layer of resin adhesive liquid of brush of carbon cloth.Backform is turned into die cavity in upper position
Put, same method carries out prepreg or carbon cloth laying.
3. cementing structure is completed
According to GB/T 7124-2008, there is the overlap of 12.5mm between sample.Therefore brushed in uncured composite material surface
Pasty state cement is coated with membranaceous cement.
4. matched moulds
Bed die and backform are slowly holded up, and is grouped together as requested, be fixed with fastening bolt.In order to ensure sample
Pressure is uniform, and four bolts of frock should be tightened as far as possible.
（3）Solidification
Curing process according to composite product carries out hot setting.
（4）The demoulding
After the completion for the treatment of sample with frock hot setting, room temperature is cooled to stove.Fastening bolt is opened, will with ripping bar or screwdriver
Bed die and backform are separated, and are removed co-curing and are glued shearing sample blank.
（5）Machine adds
According to GB/T 7124-2008, by a width of 25mm of sample blank machine addition, a length of 187.5mm（Bonding plane need to be in centre）
Standard specimen.
The co-curing that the present invention is provided is glued shearing sample and prepares frock, can make and be tried with the splicing of composite co-curing
Sample, template shape chamber size is designed according to GB GB/T 7124-2008.
The present invention it is machined go out co-curing be glued shearing sample frock, and can prepare co-curing be glued shearing sample.It is logical
Test of many times is crossed, the frock is easy to use, simple.
