Description
Technical field
The invention belongs to antenna back frame or antenna support arm molding technology thereof field, and in particular to one kind carries metal joint
Carbon fiber antenna support arm moulding process.
Background technology
For simple hollow closed composite products, existing moulding process is typically using the life of inflatable moulding process
Production.Main method is：EPS (Poly Foam) foam is produced as core by product inwall and shape, and by product inwall and shape
Produce nylon wind pipe；Then EPS cores are loaded after nylon wind pipe, wind air in tube is extracted out using air pump, makes nylon wind pipe
By core tight, as inflatable body；Carbon fibre material is wrapped in inflatable body surface face again, is together put into mould,
Heating mould after matched moulds fixation, and be passed through gas into nylon wind pipe makes to be brought into close contact between every layer of the carbon fiber of periphery parcel,
Be heating and curing shaping.This method is mainly used in the simple hollow closed composite products of shaping, the metal connection of composite
Position can only be fixed using adhesion process.
However, for baroque special-shaped carbon fiber product, such as antenna back frame or antenna support arm carbon fiber composite
Material wraps up on inflatable body, winds, it is relatively difficult to overlap, and it is even to easily cause product wall unevenness, product overall mechanical properties
Decline, and have that metalwork later stage bonding is not firm, core Remained mass after high-temperature shrinkage is not easily taken out in workpiece waits scarce
The factor of falling into.
The content of the invention
The technical problems to be solved by the invention are to connect with metal there is provided one kind for above-mentioned the deficiencies in the prior art
The moulding process of the carbon fiber antenna support arm of head.The technique need not use core, reduce the shaping of carbon fiber antenna support arm
Cost, while reducing existing moulding process because the drawbacks of residue can not thoroughly take out after core heat shrinkable；The technique is adopted
With successively laying carbon fiber prepreg formation carbon fiber layer, it is to avoid the product thickness that is come due to winding lap belt is uneven to be showed
As；By retaining pre- positioned at the product carbon fiber reserved with metal joint connecting portion when folding reserved carbon fiber prepreg
Leaching material, the metal joint for offering blind hole, which is inserted in lower mould, makes the carbon fiber prepreg of reservation be located at the blind hole of metal joint
It is interior, the one-step solidification moulding of metal joint and carbon fiber antenna support arm is realized, good forming effect is connected firmly, reduced existing
There is the gluing shaping of technique later stage metal joint.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of carbon fiber with metal joint day
The moulding process of line support arm, it is characterised in that comprise the following steps：
Step 1: making mould according to the shape and size for the carbon fiber antenna support arm to be molded, the mould includes
Upper die and lower die；
Step 2: opening up blind hole on metal joint；
Step 3: carbon fiber prepreg formation carbon fiber layer is successively laid on the cavity inner wall of lower mould, during laying under
The outside length in reserve of mould not less than lower mould housing width carbon fiber prepreg, it is to be laid after the completion of nylon wind pipe is placed in
It is equipped with the lower mould of carbon fiber prepreg；Then reserved carbon fiber prepreg is folded closes the cavity of lower mould, folds
When retain and be located at the carbon fiber prepreg that carbon fiber antenna support arm and metal joint connecting portion are reserved, and will be opened up in step 2
The carbon fiber prepreg of reservation is set to be located in the blind hole of metal joint in the lower mould of metal joint insertion for having blind hole；Again by upper mould with
Lower mould matched moulds；The shape of the nylon wind pipe is engaged with the shape for the carbon fiber antenna support arm to be molded, on nylon wind pipe
Be provided with makes the valve of nylon wind pipe inflatable for being ventilated into nylon wind pipe；
Step 4: the mould after matched moulds in step 3 is heated into 60 DEG C~70 DEG C on moulding press, then pass through valve
Ventilated into nylon wind pipe, the air pressure of ventilation is 0.5MPa~0.8MPa, then under conditions of Continuous aeration mould continued plus
Insulation 30min~60min makes the carbon fiber prepreg curing molding of laying after hot to 100 DEG C~120 DEG C；
Step 5: being stripped after the mould after being incubated in step 4 is taken out, valve is then opened, nylon wind pipe is extracted out,
Obtain the carbon fiber antenna support arm with metal joint.
The moulding process of above-mentioned a kind of carbon fiber antenna support arm with metal joint, it is characterised in that in step 2
The groove being engaged with valve is offered on the upper die and lower die.
The moulding process of above-mentioned a kind of carbon fiber antenna support arm with metal joint, it is characterised in that in step 2
Successively during laying carbon fiber prepreg, the position for opening up screwed hole and pin-and-hole is needed to be respectively provided with carbon fiber antenna support arm
Metal embedded part.
A kind of moulding process of above-mentioned carbon fiber antenna support arm with metal joint, it is characterised in that the metal
Built-in fitting is arranged on the middle part of carbon fiber layer through-thickness.
A kind of moulding process of above-mentioned carbon fiber antenna support arm with metal joint, it is characterised in that the metal
Built-in fitting is aluminium alloy built-in fitting.
The present invention has advantages below compared with prior art：
1st, moulding process of the invention need not use core (eps foam), reduce the shaping of carbon fiber antenna support arm
Cost, while reducing existing moulding process because the drawbacks of residue can not thoroughly take out after core heat shrinkable.
2nd, the present invention is using successively laying carbon fiber prepreg formation carbon fiber layer, it is to avoid come due to winding lap belt
The uneven phenomenon of product thickness；It is located at product and metal joint connecting portion by retaining when folding reserved carbon fiber prepreg
The reserved carbon fiber prepreg in position, the metal joint for offering blind hole, which is inserted in lower mould, is located at the carbon fiber prepreg of reservation
In the blind hole of metal joint, metal joint and carbon fiber antenna support arm one-step solidification moulding, good forming effect, connection jail are realized
Gu, reduce the gluing shaping of existing process later stage metal joint.
3rd, the present invention preferably needs the position for opening up screwed hole and pin-and-hole to set metal embedded part in carbon fiber antenna support arm,
Carbon fiber antenna support arm after shaping can punch at the position that be provided with metal embedded part, it is to avoid due to carbon fiber product wall thickness
It is relatively thin to cause the problems such as punching easily crackle occurs.
4th, the carbon fiber antenna support arm good mechanical performance being molded using the method for the present invention, meets client's use requirement.
