Description
Technical field
The present invention relates to composite material manufacturing technology, particularly relate to a kind of fibre reinforced thermoplastic composite manufacture method.
Background technology
Fibre reinforced thermoplastic composite take carbon fiber as reinforcing material, thermoplastic resin is the high-performance composite materials that matrix is produced, have quality light, intensity is large, corrosion-resistant, long service life, the feature that impact resistance is high, and relative to carbon fiber-reinforced thermosetting composite, can be again shaping after its heating, be a kind of green recyclable material, therefore attract attention and study.
The manufacture method of current fibre reinforced thermoplastics type composite mainly contains melt impregnation, powder infusion method, carbon fiber/matrix fiber blending method, melt film method etc., all all adopt certain method by fiber and matrix resin mixing, heated resin makes it to melt, and impregnation of fibers, then cooling and shaping obtains carbon fibre reinforced composite.But because thermoplastic resin molecular weight is high, therefore very large viscosity is still had in the molten state, often cannot good impregnation of fibers, do not become good resin/fibre section, cause composite property not high, and want complete molten resin also to need regular hour and energy consumption, especially to process the larger product of thickness and can bring very large difficulty.
Summary of the invention
(1) technical problem that will solve
The object of this invention is to provide a kind of method manufacturing fibre reinforced thermoplastic composite, enable thermoplastic resin and fiber form good cross section, improve the performance of composite, and realize the larger product of processing thickness at short notice.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of fibre reinforced thermoplastic composite manufacture method, it comprises the steps:
Step (1): carbon fiber and thermoplastic resin are replaced lay and enters in mould, the mould bottom and the superiors are thermoplastic resin, mold closing applies pressure;
Step (2): at carbon fiber layer access power supply, make it to be rapidly heated under the function of current, temperature is higher than after thermoplastic resin fusing point, and thermoplastic resin starts melting, under stress impregnation of carbon fibers;
Step (3): deenergization, die sinking after mold cools down, obtains fibre reinforced thermoplastic composite.
Wherein, described carbon fiber is any one in carbon fiber wire, carbon fibre fabric, carbon fiber grille, carbon fiber felt, carbon fiber and other fiber hybrid fabrics, carbon fiber and other fiber hybrid felts, carbon fiber/resin compounded muscle, carbon fiber/resin compounded grid.

Wherein, in described step (2), the electric current passed into during access power supply in carbon fiber layer is 1-10A.
(3) beneficial effect
The fibre reinforced thermoplastic composite manufacture method that technique scheme provides, with carbon fiber originally as heater, because carbon fiber belongs to random graphits structure, diameter is thin, external surface area is large, the heat produced after energising is easy to distribute, and electric heating conversion efficiency is up to more than 90%, and energy-saving effect is very remarkable; Simultaneously, because carbon fiber completes dipping at inner ablation heat plastic resin, there is the advantage that molding time is short, dipping effect is good, thermoplastic resin and the good cross section of processbearing astrocyte can be realized, improve the performance of composite, and realize the larger product of processing thickness at short notice.
Detailed description of the invention
Below in conjunction with embodiment, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
The present embodiment provides a kind of fibre reinforced thermoplastic composite manufacture method, and it comprises the steps:
Step (1): carbon fiber and thermoplastic resin are replaced lay and enters in mould, the mould bottom and the superiors are thermoplastic resin, mold closing applies pressure;
Step (2): at carbon fiber layer access power supply, make it to be rapidly heated under the function of current, temperature is higher than after thermoplastic resin fusing point, and thermoplastic resin starts melting, under stress impregnation of carbon fibers;
Step (3): deenergization, die sinking after mold cools down, obtains fibre reinforced thermoplastic composite.
Wherein, in above-mentioned manufacture method, described carbon fiber is any one in carbon fiber wire, carbon fibre fabric, carbon fiber felt, carbon fiber and other fiber hybrid fabrics, carbon fiber and other fiber hybrid felts; Described thermoplastic resin is any one in polyethylene, polypropylene, polyvinyl chloride, polyurethane, Merlon, polyformaldehyde, nylon, polytetrafluoroethylene (PTFE), polyether-ether-ketone; Described thermoplastic resin is resin molding, resin powder, masterbatch resin or resin prefabricated component.
Further, in above-mentioned manufacture method, according to the type of thermoplastic resin used, mold closing applied pressure is between 10-50MPa, and this pressure is too large, and carbon fiber layer can by resin punching distortion, and this pressure is too little, and resin cannot abundant impregnation of fibers; According to the thickness of product, the type of thermoplastic resin used, the electric current passed into during carbon fiber layer access power supply is 1-10A, and this electric current is excessive, temperature can be made too high, destroy resin structure, even resin is burnt, this electric current is too small, and resin viscosity is large, cannot abundant impregnation of fibers.
Said method may be used for manufacturing fibre reinforced thermoplastic PVC well lid, and its process is as follows:
First thermoplastic prefabricated component A1 and thermoplastic plastic prefabricated component B3 is obtained by the method for injection moulding or mold pressing;
Carbon fibre fabric is put between thermoplastic prefabricated component A1 and thermoplastic plastic prefabricated component B3, then put into mould;
Electrified regulation, polyvinyl chloride resin starts melting, impregnation of carbon fibers fabric;
After having flooded, power-off cools, and obtains fibre reinforced thermoplastic PVC well lid.
This kind of method technique is simple, and energy consumption is low, soon shaping, and obtained fibre reinforced thermoplastic PVC well lid quality is light, and intensity is large, and impact resistance is superior.
As can be seen from the above embodiments, the present invention with carbon fiber this as heater, because carbon fiber belongs to random graphits structure, diameter is thin, and external surface area is large, and the heat produced after energising is easy to distribute, electric heating conversion efficiency is up to more than 90%, and energy-saving effect is very remarkable; Simultaneously, because carbon fiber completes dipping at inner ablation heat plastic resin, there is the advantage that molding time is short, dipping effect is good, thermoplastic resin and the good cross section of processbearing astrocyte can be realized, improve the performance of composite, and realize the larger product of processing thickness at short notice.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
