Description
Technical field
The present invention relates to new-energy automobile Material Fields, and in particular to composite thermoplastic carbon fiber material and its melt impregnation
Technique.
Background technique
Carbon fibre composite is an important branch in composite material, since it has excellent performance, this material in recent years
The purposes and yield of material gradually expand.For a long time, carbon fibre reinforced composite is counted as a kind of material of valuableness, price
About ten times of glass fibre reinforced composion are served only for the sophisticated technologies industry such as military project, aerospace.In recent years, carbon fiber is every
Year is increased with 50% or more speed, wherein there are two the development that key factor has pushed carbon fibre composite, first is that above-mentioned
Deepening continuously for material understanding, makes its performance be gradually improved, can reach the performance that many other materials hardly match, it is promoted to make
Dosage constantly rises.Second is that the continuous reduction of cost effectiveness, this be mainly attributed to Industry of Carbon Fiber can provide the fiber of high quality with
And fiber/matrix melting technology is constantly progressive.The large-scale production of carbon fiber, makes its Quality advance and price declines, and adds
The progress of work technology make again be added composite material in carbon fiber dimensional ratio constantly rise, at present up to volume ratio 60% with
On.
Carbon fibre composite development is like a raging fire, breaks with tremendous force.Thermosetting is mostly applied in space flight and aviation and national defense industry
Property composite material, however same with thermosetting compound material is at high cost, and molding cycle is long, and greatest problem is difficult to recycle, and pollutes environment
Consequence is serious.By being dedicated to base-material research and development for many years, successively select PC, PEEK, PPS, PI, PA, PET, PP as the examination of base-material
It tests.From the experiment, it was found that PA is a kind of particularly important thermoplastic web.Though PA itself is the engineering plastics haveing excellent performance, inhale
Moist big, product size stability is poor, and intensity and hardness are also nothing like metal, in order to overcome these disadvantages, using carbon fiber
Or the fiber of other kinds is enhanced to improve its performance.It has developed rapidly in recent years with fibre reinforced PA material, because of PA
It is all the material that engineering plastics field is had excellent performance with carbon fiber, the compound synthesis of the two embodies respective advantage, intensity and just
Property it is more much higher than non-reinforced nylon, creep is small, and dimensional accuracy is good, and thermal stability significantly improves, and wear-resisting, damping and amortization is excellent, with
Fiberglass reinforced, which is compared, better performance.But the carbon fibre composite that PA is base-material is still existed at present to the feelings of higher cost
Condition.
And in carbon fibre composite research and development, the interface cohesion technology and melt impregnating process of resin matrix and carbon fiber
The key technology prepared, there are many current melt impregnating process, and include: 1, film laminates method, by carbon fiber one-way band or
Woven fabric is alternately laminated with resin film, and then heating pressurization is embedded in carbon fiber equably in resin film, this method
It is using earliest one of impregnation technology, suitable for any thermoplastic resin that can be film-made.But made of this technique
Composite material, since molten resin viscosity is high, cannot impregnation of carbon fibers or woven fabric well, thus composite property compared with
It is low；2, calendering infusion process is squeezed into resin melt in carbon fiber bundle by a pair of heterodromous pressure roller, and the method process connects
Continuous, production efficiency improves, but laminates that method is the same, and this method is difficult that carbon fiber bundle is made to obtain good dipping with film；3, it applies
Method prepares unidirectional fibre enhancing thermoplastic resin prepreg commercialized method earliest, is using intersection mouth mold to continuous fiber
Carry out extrusion coating.For the method since impregnation pressure is lower, fiber impregnation is incomplete, and fiber can hardly completely attach in beam
Resin；4, melt injects prepreg method, currently, foreign study develops melt injection prepreg method and a kind of new preimpregnation tool is pre-
Leaching wheel.Melt injection prepreg method be by fiber from two or more formers can be pulled through on the nozzle of injecting resin melt,
Fiber is dispersed in melt, to achieve the purpose that impregnate fiber.Wherein by the molten resin of nozzle, supplied by extruder.
Pass through in the short time of nozzle since the dipping of this method only occurs in fibre bundle, therefore, in order to ensure that resin is to the abundant of fiber
Dipping, it is necessary to apply certain tension to fiber, is in close contact it with nozzle, meanwhile, the melt sprayed from nozzle must have
There is certain pressure.
By described above, the technique of the melt impregnation of carbon fibre composite need to be advanced optimized at present.
