Interior die pressing product, when first making timber or bamboo wood and iron staff when coiled strip under being needed for product size internal diameter by resistance to, so
Nylon wind pipe is enclosed on afterwards and makees strip by resistance to upper bag fiber cloth, the both ends of nylon wind pipe will grow the fiber length of structure design
Degree, the greenware condition by pre- pattern pre-shaped into product, the valve of air inlet when one end of nylon tube is wrapped with shaping, pre-shaped
Good semi-finished product are put into be sent into have in mould and pressurizeed on the workbench of temperature, and the air inlet pipe on workbench is finally inserted gas
The aeration of mouth progress multisection type admission pressure about 30 minutes, the demoulding can obtain the thick embryo of product.But occur during aeration
Gas leakage and to be directed at product strength relatively low and scrap.2nd, whole branch is all using the direct external pressure of fiber, or with containing Polyurethane (poly- first
Base acrylimide) core make filling come the outer die pressing product of the carbon fiber that makes, take polyurethane A (black material)/B (white material) by 1:1
Ratio stir in the mould for pouring into design and (or directly take the polyurethane materials sent out to carry out product size
Cut) core can be obtained, directly fibrous material is wrapped up according to product structure design order semi-finished product are obtained on core, be put into
Workbench heating pressurization 30 minutes is sent into pattern tool, the demoulding can obtain the thick embryo of product, but can cause the defects of product appearance,
Serious meeting causes product.
The content of the invention
The present invention is to solve the requirement of the manufacture property of carbon fiber product, there is provided a kind of shaping of carbon fiber product
Technique, the moulding process is not under conditions of solving production, it is ensured that product appearance, so as to lift quality state and reduce system
Cause this.
Technical scheme is as follows：A kind of moulding process of carbon fiber product, it is characterised in that including following process：

After being evaporated completely Deng acetic acid formicester, mould is put into after fibrous material will be bandaged by the structure of products made thereby outside above-mentioned inner core material
Interior, the expanded material that pressurization allows in inner core material at 150 DEG C expands 30~40 minutes, obtains the thick embryo of one-shot forming product.
Technical scheme can also be：A kind of moulding process of carbon fiber product, it is characterised in that including as follows
Process：（1）Prepare expanded material：Acrylic microspheres particle is added into epoxy resin and acetic acid formicester, stirs, obtains together
Expanded material；（2）Expanded material is handled to the adhesive-bonded fabric of the die pressing product in carbon fiber with hairbrush or spray gun and the mode of impregnation
On；（3）After being evaporated completely Deng acetic acid formicester, above-mentioned adhesive-bonded fabric is cut according to products made thereby size, then is not knitted what is cut out
Cloth is wrapped with fibrous material, is put into after bandaging above-mentioned fibrous material according still further to product design order in mould, at 150 DEG C
The expanded material that lower pressurization allows on adhesive-bonded fabric expands 30~40 minutes, obtains the thick embryo of one-shot forming product.
Epoxy resin of the present invention, acetic acid formicester and steep the percentage by weight of powder epoxy resin and be：Epoxy resin 35
~40%, acetic acid formicester 35~40%, acrylic microspheres particle 20~30%.
Inner core material of the present invention is the inner core material containing Polyurethane or Polymethacrylimide.
Fibrous material of the present invention is UD one directions cloth or textile sheet.
The acrylic microspheres particle of the present invention can be replaced with other foaming powders.
The present invention be put into expanded material among the fiber of die pressing product in carbon fiber, can drop light product weight and into
This, ensure that the appearance of Related product, or the inner core material surface of die pressing product is put into expanded material outside carbon fiber, can solve
Certainly the defects of product appearance and scrap.
