Abstract
The invention provides a carbon fiber composite material specially-shaped product forming process. The carbon fiber composite material specially-shaped product forming process is characterized by comprising the following steps: A. manufacturing a foaming core material: manufacturing a core material by flexible foaming materials such as expandable polystyrene, wherein the shape of the core material is as the same as that of the product scaling down at equal proportion; B. welding an air duct: cutting a nylon film material into the shape formed by scaling up the product at equal proportion, preserving air nozzle holes, welding the edge of the nylon film by an ultrasonic wave welding mode so as to form a specially-shaped enclosed space, and meanwhile sealing the core material obtained from the step A into the nylon film so as to form a specially-shaped air pipe; C. pre-molding: laminating and pre-molding a product structure on the specially-shaped air pipe by pre-immersed carbon fiber composite materials so as to form a pre-molding body; and connecting air nozzles on air nozzle hole parts of the step B after laminating and pre-molding; D. forming; and E. taking out auxiliary materials. The carbon fiber composite material specially-shaped product forming process provided by the invention can integrally form various complex modeling products, and can enable the auxiliary materials such as the nylon film to be separated from the carbon fiber composite material product smoothly.
Description
Technical field
The invention belongs to a kind of forming method of carbon fibre composite product.
Background technology
Traditional carbon fibres composite products carries out lamination and operations for forming with tubulose nylon wind pipe conventionally, and this kind is mainly used for circular tube shaped product.In recent years, there are a lot of special-shaped products in carbon fibre composite class market, and such as the break bar wheel rim product of the car of competing for speed for highway timing car and place, variation in moulding is various.But traditional processing technology is difficult, minority manufacturer is used emulsion air pocket to add expanded material explained hereafter, but complex manufacturing, yields is low, and manual operation ratio is very large, causes production efficiency low, and quality is unstable, cannot produce in a large number.
Summary of the invention
The invention provides a kind of carbon fibre composite special-shaped product moulding process, its objective is and solve the shortcoming that prior art exists, can one-body molded various complex model products, and can make the auxiliary materials such as nylon film can be smoothly and the disengaging of carbon fibre composite product.
The technical solution adopted for the present invention to solve the technical problems is:
A special-shaped product moulding process, is characterized in that: comprise the steps:
A: foamed core material is made:
Use the flexible foamed materials such as Poly Foam to make core, core is shaped as product scaled down;
B: airduct welding:
Nylon film material is cut into the shape that the equal proportion more bigger than product amplified, reserved air nozzle hole, is used ultrasonic bonding mode that nylon film edge is welded, and forms a special-shaped confined space, core steps A being obtained is sealed in nylon film simultaneously, forms special-shaped airduct;
C: pre-type:
Use the carbon fibre composite of preimpregnation on special-shaped airduct, to complete the pre-type formation of product structure lamination preform; After the pre-type of lamination completes, in the air nozzle hole position described in step B, connect valve;
D: moulding:
The preform that step C obtains is put into mould, and heating mould, to 150-160 degree Celsius, is filled with the above gases at high pressure of 8bar from valve simultaneously, carries out operations for forming;
E: take out auxiliary material:
After moulding, product surface punching, together takes out nylon film material together with the auxiliary materials such as expanded material after dwindling, and obtains carbon fibre composite special-shaped product.
Usefulness of the present invention is:
The present invention adopts nylon-type film slitting to be processed into shape of product, and overlay on expanded material, and by equipment automatic welding edge line, make the even mulching of nylon film on expanded material, and be an airtight special-shaped cavity after welding, for being filled with hyperbar at internal cavities, the lightweight special-shaped product of at high temperature moulding.This kind of processing technology can keep disengaging technology after the moulding of nylon film and carbon fibre composite product maturation, be easy to after moulding by the auxiliary material such as nylon film expanded material smoothly with the disengaging of carbon fibre composite product.And use automatic welding equipment to guarantee product with stable quality.Interiors of products structure is sturdy, and in same weight situation, intensity can improve 15%-25%, simultaneously can one-body molded various complex model products.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is special-shaped air duct structure figure of the present invention;
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
The present invention includes following steps:
A: foamed core material is made:
Use the flexible foamed materials such as Poly Foam to make core 2 (as Fig. 2), core 2 is shaped as product scaled down, for the pre-type of later stage product; The Poly Foam approximately 20 times of expansion ratios that foam, can shorten very small size into after high temperature, are easy to take out from product;
B: airduct welding:
Nylon film material is cut into the shape that the equal proportion more bigger than product amplified, reserved air nozzle hole 10, use ultrasonic bonding mode that nylon film edge is welded, form a special-shaped confined space, core steps A being obtained is sealed in nylon film simultaneously, forms special-shaped airduct 1 (as Fig. 1);
C: pre-type:
Use the carbon fibre composite of preimpregnation on special-shaped airduct 1, to complete the pre-type of product structure lamination and form preform, now special-shaped airduct inner side is because the existence of the core 2 that expanded material is made, and makes the lamination procedure easy operating that becomes; After the pre-type of lamination completes, in air nozzle hole 10 positions described in step B, connect valve;
D: moulding:
The preform that step C obtains is put into mould, and heating mould, to 150-160 degree Celsius, is filled with the above gases at high pressure of 8bar from valve 10 simultaneously, carries out operations for forming; Gases at high pressure, in special-shaped airduct 1, become more sturdy the preform in hot setting process; The core 2 that foamed material is made simultaneously becomes very little in high temperature and high pressure gas lower volume, is easy to lower operation and takes out;
E: take out auxiliary material:
After moulding, product surface punching, together takes out nylon film material together with the auxiliary materials such as expanded material after dwindling, and obtains carbon fibre composite special-shaped product.
